₃-Oxido-hexa-₂-pivalato-tris[(methanol-O)cobalt(III)] chloride

Y. Sun, L.-L. Zhu and H.-H. Zhang

Abstract: The crystal structure of the title compound, [Co₃(C₅H₉O₂)₆O(CH₄O)₃]Cl, consists of trinuclear Co^III complex cations and chloride anions. The Co^III cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octahedral geometry. The coordinated methanol molecule is located on a crystallographic special position, the C and O atoms being located on the mirror plane. The central O anion lies in the crystallographic position, and acts as a ₃-O bridge, linking three equivalent Co^III cations and generating the oxo-centered trinuclear Co^III complex. The chloride anion, which acts as the counter-ion, is located on crystallographic position. O-HCl hydrogen bonding between the Cl anion and hydroxyl group of the coordinated methanol molecule links the molecules into a supramolecular network.
