摘 要: | The crystal structure of CoCl ( C7H5N2CH2COPh)4] Br has been determined by means of X-ray crystallography. The molecular structure consists of a discrete CoCl ( C7H5N2CH2COPh)4] ^ cation and one Br^- anion, in the CoCl ( C7H5N2CH2COPh)4]^ cation, the coordination geometry of the central Co atom is square-pyramidal with four tertiary N atoms of benzimidazole from four α-( benzimidazol-1-yl) -hypnone ligands in the basal position and one chloride anion in the apical position. In the solid state, CoCl ( C7H5N2CH2COPh)4]^ and Br^- anion possess intermolecular and intramolecular interactions, which stabilize the crystal structure. The characterization of the title compound were also carried out by using elemeutal analysis, FTIR, UV spectrometries and TG-DSC.
