Bis[2-hydr-oxy-N'-(2-hydroxy-benzo-yl)benzohydrazitato]dipyridine-cadmium(II).

ABSTRACT: The title complex, [Cd(C(14)H(11)N(2)O(4))(2)(C(5)H(5)N)(2)], exhibits crystallographic twofold symmetry. The Cd(II) atom is located on the twofold rotation axis and reveals a slightly distorted octa-hedral coordination defined by four atoms (N(2)O(2)) from two symmetry-related chelate ligands and two pyridine N atoms. Intra-molecular O-H?O and N-H?O hydrogen bonds stabilize the mol-ecular conformation while inter-molecular O-H?O hydrogen bonding links mol-ecules into a triad, generating a helix along the threefold screw axis.
