✦ Synopsis

In the title compound, [Cu(Cl~2~CHCO~2~)~2~(C~6~H~6~N~2~O)~2~(H~2~O)], both the Cu^II^ atom and the O atom of the coordinated water molecule lie on a crystallographic twofold rotation axis. The Cu^II^ atom is coordinated by O atoms from two monodentate chloroacetate anions, pyridine N atoms from two monodentate nicotinamide ligands and by the water molecule, forming a tetragonal–pyramidal coordination polyhedron. The complexes are linked by O—H...O, N—H...O and C—H...O hydrogen bonds into a three-dimensional network.
