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

Y.-T. Chen and D.-C. Li

Abstract: The title complex, [Cd(C₁₄H₁₁N₂O₄)₂(C₅H₅N)₂], exhibits crystallographic twofold symmetry. The Cd^II 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-HO and N-HO hydrogen bonds stabilize the molecular conformation while intermolecular O-HO hydrogen bonding links molecules into a triad, generating a helix along the threefold screw axis.
