Bis[4'-(4-cyanophenyl)-2,2':6',2''-terpyridine]cobalt(II) dichloride

K. Qian, Z.-H. Yan and Z.-W. Chen

Abstract: The title complex, [Co(C₂₂H₁₄N₄)₂]Cl₂, has been synthesized by a solvothermal reaction of the 4'-(4-cyanophenyl)-2,2':6',2''-terpyridine ligand with CoCl₂·6H₂O. The cobalt(II) ion is six-coordinated by two tridentate ligands in a distorted octahedral geometry. The benzene rings form dihedral angles of 30.02 (7) and 30.26 (7)° with the mean planes of the terpyridine ring systems. The chloride anions are statistically disordered over two positions with refined site occupancies of 0.601 (2) and 0.399 (2).
