✦ Synopsis

n-Propyl gallate (PG) is a charge-control agent used for toners in electrophotography, and shows pseudo-polymorphism. The title compound, 3C 10 H 12 O 5 Á0.5CH 2 Cl 2 , is isostructural with the corresponding chloroform solvate. The asymmetric unit is composed of three PG molecules and a half-molecule of dichloromethane, the solvent being disordered over an inversion centre. There are intra-and intermolecular O-HÁ Á ÁO hydrogen bonds, forming a two-dimensional hydrogenbond network in the (421) plane.

In the title complex, [CuCl~2~(C~31~H~28~N~6~)]·0.5C~2~H~3~N, the Cu^2+^ atom is coordinated in a distorted square-pyramidal geometry by three N atoms from the pyrazolyl groups of the tripodal ligand, and by two chloride anions.
