title: {4,6-Bis[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene-κN)hydrazinyl-κN]pyrimidine-κN}dichloridocopper(II) methanol disolvate monohydrate.
abstract: The title compound, [CuCl(2)(C(18)H(18)N(8))]·2CH(3)OH·H(2)O, contains a penta-coordinated Cu(II) atom bonded to the tridentate 4,6-bis-[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene)hydrazin-yl]pyrimidine ligand and two Cl atoms. The geometry around the Cu(II) atom is distorted square-pyramidal. The mol-ecules 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 inter-actions [centroid-centroid distances of the pyrimidine-pyridine and pyridine-pyridine inter-actions are 3.750 (3) and 3.850 (3) Å, respectively], forming sheet-like assemblies.
