Bis[2-hydroxy-N′-(2-hydroxybenzoyl)benzohydrazitato]dipyridinecadmium(II)

Abstract

The title complex, [Cd(C14H11N2O4)2(C5H5N)2], exhibits crystallographic twofold symmetry. The CdII atom is located on the twofold rotation axis and reveals a slightly distorted octahedral coordination defined by four atoms (N2O2) from two symmetry-related chelate ligands and two pyridine N atoms. Intramolecular O—H...O and N—H...O hydrogen bonds stabilize the molecular conformation while intermolecular O—H...O hydrogen bonding links molecules into a triad, generating a helix along the threefold screw axis.
