Metal Complexes of Aroyl(acyl)benzoylhydrazones of Aromatic Aldehydes and Ketones: Coordination Modes and Properties

Abstract

The data based on the X-ray diffraction analysis results obtained within the recent 20 years about the coordination modes of aroyl(acyl)hydrazones of aldehydes and ketones containing chelatophoric groups of atoms and their photoluminescence and magnetic properties and biological activity are reviewed and generalized. The most significant earlier studies of the metal complexes with the aroyl(acyl)hydrazone ligands are also considered. This review is fruitful for researchers specialized in the target synthesis of new metal complexes of the ligands of this class aimed at manufacturing practically important materials based on these complexes.
