Abstract

The title copper(II) complex, {[CuCl(C(15)H(16)N(4)O(2))]Cl.0.61H(2)O}(n), is a one-dimensional zigzag coordination polymer structure extending along the (010) direction. The Cu(II) atom has a square-pyramidal geometry, where the basal plane is formed by two cis N atoms and one O atom from the ligand, and by a Cl atom. The apical position is occupied by a carbonyl O atom from a symmetry-related molecule. In the crystal structure, there are O-H...Cl and N-H...Cl hydrogen bonds, which link parallel polymer chains along the c direction, so building a two-dimensional structure via the interstitial Cl atoms.
