Abstract
Single crystal X-ray structure of monoatomically bridged [6,6'-μ-S(1,7-C2B9H10)2-2-Co]-[PPh4]+ is reported and selected bond lengths and angles are tabulated. A distinctly smaller dihedral angle (12.2°) between both pentagonal ligand planes than found earlier in the formally related symmetric analogue 8,8'-μ-MeOCOCH2S(1,2-C2B9H10)2-3-Co (16.5°) is discussed. This is the first reported X-ray structure of a monoatomically bridged cobaltacarborane with nonadjacent carbon atoms in deltahedral ligands.
Keywords: S-Bridged cobaltacarborane with nonadjacent C-atoms, structure; Inclination of ligand planes.
