✦ Synopsis

The crystal structure of a Co II complex with 1,4-diazacycloheptane (DACH) functionalized by two additional pyridine donor pendants, [CoCl(L)](ClO 4 ), where L = 1,4-bis(pyridyl-2-ylmethyl)-DACH (C 17 H 22 N 4 ), has been determined by X-ray diffraction analysis. In the mononuclear complex, the Co II center is pentacoordinated by the four nitrogen donors of the ligand and one axial chloride anion, resulting in a coordination sphere intermediate between ideal squarepyramidal and trigonal bipyramidal. It forms a one-dimensional linear structure through intermolecular CÐHÁ Á ÁCl and CÐHÁ Á ÁO hydrogen-bonding interactions.
