{-1,5-Bis[(E)-1-(2-pyridyl)ethylidene]carbonohydrazidato(1-)}bis[chloridomethanolcopper(II)] perchlorate

W. Huang

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 Cu^II ions, one of which is coordinated by pyridyl N, hydrazyl N and carbonyl O atoms. The second Cu^II ion is coordinated by the pyridyl N and two hydrazyl N atoms from different hydrazyl groups. The coordination environments of both Cu^II 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-HO(perchlorate), O-HCl and N-HCl hydrogen bonding.
