Abstract
The title dinuclear copper complex, [Cu2(C15H15N6O)Cl2(CH3OH)2]ClO4, was prepared by the reaction of copper(II) chloride with bis[1-(2-pyridyl)ethylidene]carbonohydrazide in the presence of sodium perchlorate in a methanol solution. It features a mono-deprotonated bis-tridentate ligand, which coordinates to two independent CuII ions, one of which is coordinated by pyridyl N, hydrazyl N and carbonyl O atoms. The second CuII ion is coordinated by the pyridyl N and two hydrazyl N atoms from different hydrazyl groups. The coordination environments of both CuII ions are completed by a chloride ion and a methanol molecule. The dihedral angle between the pyridyl groups is 27.46 (10)°. The crystal packing is stabilized by O—H⋯O(perchlorate), O—H⋯Cl and N—H⋯Cl hydrogen bonding.
