Bis[bis-(1-oxo-2-pyrid-yl)-aminato]-copper(II) tetra-hydrate

Abstract

In the title compound, [Cu(C(10)H(8)N(3)O(2))(2)]·4H(2)O, the Cu(II) ion has a distorted octa-hedral coordination formed by four O [Cu-O = 2.051 (3)-2.083 (4) Å] and two N [Cu-N = 1.985 (4) and 1.996 (4) Å] atoms from two tridentate bis-(1-oxo-2-pyrid-yl)aminate ligands. In the two ligands, the pyridyl rings form dihedral angles of 21.0 (1) and 15.5 (1)°. The crystal packing exhibits an extensive network of O-H⋯O hydrogen bonds and π-π inter-actions proved by short distances of 3.650 (1) and 3.732 (2) Å between the centroids of pyridyl rings of neighbouring mol-ecules.
