[1,4-Bis(pyridyl-2-ylmethyl)-1,4-diazacycloheptane]chlorocobalt(II) perchlorate

Abstract: The crystal structure of a Co^II complex with 1,4-diazacycloheptane (DACH) functionalized by two additional pyridine donor pendants, [CoCl(L)](ClO₄), where L = 1,4-bis(pyridyl-2-ylmethyl)-DACH (C₁₇H₂₂N₄), 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 square-pyramidal and trigonal bipyramidal. It forms a one-dimensional linear structure through intermolecular C-HCl and C-HO hydrogen-bonding interactions.
