Tetra-kis(4-amino-pyridine-N 1)dichlorido-copper(II) monohydrate

Abstract

The asymmetric unit of the title compound, [CuCl2(C5H6N2)4]·H2O, contains two crystallographically independent complex mol-ecules and two water mol-ecules. The CuII ion in each mol-ecule is six-coordinated in an elongated octa-hedral geometry, with the equatorial plane defined by four pyridine N atoms of four amino-pyridine ligands and the axial positions occupied by two Cl atoms. In the crystal structure, mol-ecules are linked into a three-dimensional framework by C - H⋯Cl, O - H⋯Cl, N - H⋯O, N - H⋯Cl and N - H⋯N hydrogen bonds and C/N - H⋯π inter-actions involving the pyridine rings. © 2008.
