{4,6-Bis[(E)-1-methyl-2-(pyridin-2-ylmethylidene-κN)hydrazinyl-κN2]pyrimidine-κN1}dichloridocopper(II) methanol disolvate monohydrate

Abstract

The title compound, [CuCl2(C18H18N8)]·2CH3OH·H2O, contains a pentacoordinated Cu(II) atom bonded to the tridentate 4,6-bis[(E)-1-methyl-2-(pyridin-2-ylmethylidene)hydrazinyl]pyrimidine ligand and two Cl atoms. The geometry around the CuII atom is distorted square-pyramidal. The molecules pack in the crystal structure via O—H...Cl, O—H...N, C—H...Cl and C—H...O hydrogen bonds, C—H...π and π–π interactions [centroid–centroid distances of the pyrimidine–pyridine and pyridine–pyridine interactions are 3.750 (3) and 3.850 (3) Å, respectively], forming sheet-like assemblies.
