-Di-chlorido-bis-(secnidazole-κ )copper(II).

The use of acetic acid (HOAc) in a reaction between CuCl·2HO and secnid-azole, an active pharmaceutical ingredient useful in the treatment against a variety of anaerobic Gram-positive and Gram-negative bacteria, affords the title complex, [CuCl(CHNO)]. This compound was previously synthesized using ethanol as solvent, although its crystal structure was not reported [Betanzos-Lara (2013 ▸). , , 94-100]. In the mol-ecular complex, the Cu cation is situated at an inversion centre and displays a square-planar coordination environment. There is a hydrogen-bonded framework based on inter-molecular O-H⋯Cl inter-actions, characterized by H⋯Cl separations of 2.28 (4) Å and O-H⋯Cl angles of 175 (3)°. The resulting supra-molecular network is based on (18) ring motifs, forming chains in the [010] direction.
