Bis[bis(1-oxo-2-pyridyl)aminato]copper(II) tetrahydrate

L.-G. Wang

Abstract: In the title compound, [Cu(C₁₀H₈N₃O₂)₂]·4H₂O, the Cu^II ion has a distorted octahedral 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-pyridyl)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-HO hydrogen bonds and - interactions proved by short distances of 3.650 (1) and 3.732 (2) Å between the centroids of pyridyl rings of neighbouring molecules.
