Synthesis and Crystal Structure of Tris[2-(N,N-dimethyltWocarbamoyl)benzimidazolato-l]cobalt(III)

摘要

Conditions for the formation of a CoL3 complex,where L is the deprotonated benzimidazole-2-(N,N-dimethyl)carbotbioamide molecule,are studied.The structure of the complex is determined by X-ray diffraction analysis.Each ligand in crystal of the complex is bonded to the metal atom by the bidentate chelate mode at the vertices of a distorted octahedron.The S and N atoms in the octahedron are in the cis-position to each other.All bonds with the same multiplicity in the ligands and in the CoS3N3 octahedron have almost the same length.
