Aqua-chlorido(2,2':6',2''-terpyrid-yl)copper(II) chloride monohydrate

The title complex, [CuCl(C(15)H(11)N(3))(H(2)O)]Cl·H(2)O, is composed of a monocation that possesses mirror symmetry. The Cu(II) atom has a distorted square-pyramidal geometry, being coordinated by the three N atoms of the terpyridine ligand and a Cl atom in the equatorial plane, and by a water mol-ecule O atom in the axial position. The charges are balanced by a chloride anion positionally disorded over two positions related by the mirror symmetry. The compound crystallizes as a monohydrate, with the water mol-ecule also being positionally disordered over two positions related by the mirror symmetry. In the crystal, the various components of the complex are linked via O-H⋯O and O-H⋯Cl hydrogen bonds, forming a two-dimensional network in the ab plane. There are also a number of C-H⋯Cl and C-H⋯O inter-actions which stabilize the crystal structure.
