Abstract:

The CadmiumII Isophthalicacid Benzimidazole complex [Cd2(C8H4O4)2 (C7H6N2)4(H2O)3], Triqua-bis (isophthalicacidato-O,O')-tetra (benzimidazole) bis (CadmiumII),the CdII atom is coordinated by two isophthalicacid anions and two benzimidazole and one water molecule in a distorted octahedral configuration with six-coordinations geometry. And one isophthalicacid ligand chelates to the CdII atom through its one carboxylic O atoms, but the other isophthalicacid ligand chelates to the CdII atom through its two carboxylic O atoms. The same as another CdII atom. So we get a Binuclear CdII metal complexe. The fact clearly suggests not so much significant contribution from the electrostatic interaction in the Cd-O bonding in bidentate Binuclear CdII metal complexes as we gotten in mononuclear MnII metal complexes. Adjacent complex link to each other via hydrogen bonds forming the three-dimensional supramolecular structure.
