Synthesis, Crystal Structure and Characterization of α-(1-Benzimidazolyl)-hypnone Cobalt(Ⅱ) Complex:[CoCl(C7H5N2CH2COPh)
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.
