Abstract	The lowest energy structures of the manganese boronyl carbonyl Mn2(BO)2(CO)9 by more than 8 kcal/mol are found to have a single end-to-end bridging BO group bonding to one manganese atom through its boron atom and to the other manganese atom through its oxygen atom. The long Mn···Mn distances in these structures indicate the lack of direct manganese-manganese bonding as confirmed by essentially zero Wiberg bond indices. These Mn2(BO)2(CO)9 structures are favored thermochemically by more than 25 kcal/mol over dissociation into mononuclear fragments and thus appear to be viable synthetic objectives. This contrasts with the isoelectronic Cr2(CO)11 system, which is predicted to be disfavored relative to the mononuclear fragments Cr(CO)6 + Cr(CO)5. Analogous Mn2(BO)2(CO)9 structures with an end-to-end bridging CO group lie ∼17 kcal/mol in energy above the corresponding structures with end-to-end bridging BO groups. The lowest energy Mn2(BO)2(CO)9 structures without an end-to-end bridging BO group provide unprecedented examples of the coupling of two terminal BO groups to form a terminal dioxodiborene (B2O2) ligand with a B-B distance of ∼1.9 Å. Still higher energy Mn2(BO)2(CO)9 structures include singly bridged and doubly semibridged structures analogous to the previously optimized lowest energy Cr2(CO)11 structures.

Abstract	The structure of the title compound, catena-poly[[[di-μ-aqua-μ-fumarato-μ-(boric acid)-disodium]-di-μ-aqua] boric acid monosolvate], contains two crystallographically independent Na(+) cations, each being six-coordinated by one fumarate O atom, one boric acid O atom and four water O atoms in a distorted octa-hedral geometry. Adjacent [NaO(2)(OH(2))(4)] units share edges and are linked into chains propagating parallel to [100]. The free boric acid mol-ecules are connected to the chains through strong inter-molecular O-H⋯O hydrogen bonds. Additional O-H⋯O hydrogen bonds between the water mol-ecules, the free and coordinated boric acid mol-ecules and the fumarate anion lead to the formation of a three-dimensional supra-molecular structure. With the exception of the two water mol-ecules, all other atoms lie on mirror planes.

Abstract	Recently the first boronyl (oxoboryl) complex [(c-C(6)H(11))(3)P](2)Pt(BO)Br was synthesized. The boronyl ligand in this complex is a member of the isoelectronic series BO(-) → CO → NO(+). The cobalt carbonyl boronyls Co(BO)(CO)(4) and Co(2)(BO)(2)(CO)(7), with cobalt in the formal d(8) +1 oxidation state, are thus isoelectronic with the familiar homoleptic iron carbonyls Fe(CO)(5) and Fe(2)(CO)(9). Density functional theory predicts Co(BO)(CO)(4) to have a trigonal bipyramidal structure with the BO group in an axial position. The tricarbonyl Co(BO)(CO)(3) is predicted to have a distorted square planar structure, similar to those of other 16-electron complexes of d(8) transition metals. Higher energy Co(BO)(CO)(n) (n = 3, 2) structures may be derived by removal of one (for n = 3) or two (for n = 2) CO groups from a trigonal bipyramidal Co(BO)(CO)(4) structure. Structures with a CO group bridging 17-electron Co(CO)(4) and Co(BO)(2)(CO)(3) units and no Co-Co bond are found for Co(2)(BO)(2)(CO)(8). However, Co(2)(BO)(2)(CO)(8) is not viable because of the predicted exothermic loss of CO to give Co(2)(BO)(2)(CO)(7). The lowest lying Co(2)(BO)(2)(CO)(7) structure is a triply bridged (2BO + CO) structure closely related to the experimental Fe(2)(CO)(9) structure. However, other relatively low energy Co(2)(BO)(2)(CO)(7) structures are found, either with a single CO bridge, similar to the experimental Os(2)(CO)(8)(μ-CO) structure; or with 17-electron Co(CO)(4) and Co(BO)(2)(CO)(3) units joined by a single Co-Co bond with or without semibridging carbonyl groups. Both triplet and singlet Co(2)(BO)(2)(CO)(6) structures are found. The lowest lying triplet Co(2)(BO)(2)(CO)(6) structures have a Co(CO)(3)(BO)(2) unit coordinated to a Co(CO)(3) unit through the oxygen atoms of the boronyl groups with a non-bonding ∼4.3 Å Co···Co distance. The lowest lying singlet Co(2)(BO)(2)(CO)(6) structures have either two three-electron donor bridging η(2)-μ-BO groups and no Co···Co bond or one such three-electron donor BO group and a formal Co-Co single bond.

Article ; Online: Prospects for three-electron donor boronyl (BO) ligands and dioxodiborene (B2O2) ligands as bridging groups in binuclear iron carbonyl derivatives.

Abstract	Recent experimental work (2010) on (Cy(3)P)(2)Pt(BO)Br indicates that the oxygen atom of the boronyl (BO) ligand is more basic than that in the ubiquitous CO ligand. This suggests that bridging BO ligands in unsaturated binuclear metal carbonyl derivatives should readily function as three-electron donor bridging ligands involving both the oxygen and the boron atoms. In this connection, density functional theory shows that three of the four lowest energy singlet Fe(2)(BO)(2)(CO)(7) structures have such a bridging η(2)-μ-BO group as well as a formal Fe-Fe single bond. In addition, all four of the lowest energy singlet Fe(2)(BO)(2)(CO)(6) structures have two bridging η(2)-μ-BO groups and formal Fe-Fe single bonds. Other Fe(2)(BO)(2)(CO)(n) (n = 7, 6) structures are found in which the two BO groups have coupled to form a bridging dioxodiborene (B(2)O(2)) ligand with B-B bonding distances of ~1.84 Å. All of these Fe(2)(μ-B(2)O(2))(CO)(n) structures have long Fe···Fe distances indicating a lack of direct iron-iron bonding. One of the singlet Fe(2)(BO)(2)(CO)(7) structures has such a bridging dioxodiborene ligand with cis stereochemistry functioning as a six-electron donor to the pair of iron atoms. In addition, the lowest energy triplet structures for both Fe(2)(BO)(2)(CO)(7) and Fe(2)(BO)(2)(CO)(6) have bridging dioxodiborene ligands with trans stereochemistry functioning as a four-electron donor to the pair of iron atoms.

Abstract	A theoretical study on the geometries and electronic structures of W@Au(12)AE (AE=NO(+), BF, CN(-), or BO(-)) was carried out to gain insight into interactions between W@Au(12) and ligands isoelectronic with CO. The best configuration for the adsorption site is on-top type for all five complexes. After complexing with boron ligands (BF or BO(-)), the axial Au-W bond distance in W@Au(12) is lengthened notably, but NO(+) has the opposite effect on the axial Au-W bond. A charge transfer and energy decomposition analysis shows that the metal-ligand bonds have enhanced sigma-donation strength from NO(+) to BO(-). Furthermore, the A-E bond strength in the complexes becomes weaker with stronger pi-back-donation interactions. Finally, W@Au(12)CO has the largest HOMO-LUMO gap, making it the most stable in terms of kinetic stability.

Abstract	Objectives: As a common postpartum complication, postpartum depression is an important social and health problem. Postpartum depression causes many changes in relevant indicators, such as inflammatory factors and thyroid hormones. However, the effects of inflammatory factors, thyroid hormones and xanthine on postpartum depression have not yet been fully elucidated. Therefore, it is of great clinical significance to clarify the changes in the key indicators of postpartum depression. Material and methods: A total of 139 pregnant women were included in this study. Finally, only 56 patients completed the Edinburgh Depression Scale (EPDS) evaluation and blood sample collection. Results: In the current study, 34 (60.7%) patients were normal, 10 (17.9%) women were depressive tendency and 12 (21.4%) women developed depression. Among the serum indexes detected, the expression levels of thyroid function indexes T3, T4 and TSH, and inflammatory factors, such as hs-CRP, IL-1β, IL-6 and TNF-α, in the EPDS ≥ 9 group were slightly higher than those in the normal group (EPDS < 9). Xanthine levels in the depression group (EPDS ≥ 13) were significantly higher than normal group (EPDS < 9). Conclusions: Our findings suggest that xanthine levels in patients with postpartum depression were increased significantly, but there were no significant changes in thyroid function and some inflammatory indexes. Therefore, timely detection and intervention of maternal xanthine may help reduce the incidence of postpartum depression.
