Abstract

In the cationic complex present in the title compound, chloro[2-(4-imidazolyl-kappaN(1))ethylamine-kappaN](1,10-phenanthroline-kappa(2)N,N')copper(II) chloride monohydrate, [CuCl(C(5)H(9)N(3))(C(12)H(8)N(2))]Cl.H(2)O, the metal centre adopts a five-coordinate geometry, ligated by the two phenanthroline N atoms, two amine N atoms of the histamine ligand (one aliphatic and one from the imidazole ring) and a chloro ligand. The geometry around the Cu atom is a distorted compressed trigonal bipyramid, with one phenanthroline N and one imidazole N atom in the axial positions, and the other phenanthroline N atom, the histamine amine N atom and the chloro ligand in the equatorial positions. The structure includes an uncoordinated water molecule, and a Cl(-) ion to complete the charge. The water molecule is hydrogen bonded to both Cl(-) ions (coordinated and uncoordinated), and exhibits a close Cu.H contact in the equatorial plane of the bipyramid.
