Six Cu(II) complexes containing the NO2 donor tridentate asymmetrical aroylhydrazone ligand (E)-4-hydroxy-N′-((2-hydroxynaphthalen-1-yl)methylene)benzohydrazide (HL), namely, [Cu(L)Cl]·2H2O (1), [Cu(L)(CH3OH)2]·

Two novel Eu(III) complexes with notable properties have been successfully prepared with hydrazone Schiff base ligands, (E)-2-hydroxy-N'-[(2- hydroxynaphthalen-1-yl)methylene]benzohydrazide (3a) and (E)-4-hydroxy- N'-[(2-hydroxynaphthalen-1-yl)methylene]benzohydrazide (3b). DFT, FMO energy and Mulliken charge distribution studies of the ligands allowed us to hypothesize that their HC=N, >C=O and -OH (naphthyl) groups were involved in coordinating with the Eu3+ ion. The eight coordination sites of the Eu3+ ion were occupied by the three functional groups of the two ligands (3a or 3b) mentioned above and two water molecules. Similar UV, IR and fluorescence spectra indicated the presence of comparable coordination environments for the Eu3+ ion in both complexes. Both the ligands and their complexes exhibited moderate DPPH radical scavenging activity. Moreover, it was found that the Eu(III) complexes exhibited fluorescence properties.

Fourteen acylhydrazides have been condensed with three aromatic o-hydroxy aldehydes (pyridoxal, salicylaldehyde, and 2-hydroxy-1-naphthaldehyde) to give 42 acylhydrazones, of which 38 are new.These compounds complex iron and have shown varying abilities to promote the movement of iron across biological membranes.Their infrared and nuclear magnetic resonance spectra support the structures assigned to them.
