Crystal structure of ortho-rhom-bic {bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine-κ(3) N,N',N''}chlorido-copper(II) perchlorate.
In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the Cu(II) ion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitro-gen atoms from the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221 (16) and 0.145 (7). In addition, the hetero-scorpionate arm of the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand is disordered over two sets of sites with refined occupancies 0.839 (2) and 0.161 (2). In the crystal, weak Cu⋯Cl inter-actions between symmetry-related mol-ecules create a dimerization with a chloride occupying the apical position of the square-pyramidal geometry typical of many copper(II) chloride hetero-scorpionate complexes.
