Synthesis, crystal structure and spectral characterization of the first Ag+ complex compounds involving O,N,O-coordinated N-acylhydrazones of salicylaldehyde

N-acylhydrazones of salicylaldehyde is a well known class of ligands bearing O,N,O tridentate chelate coordination site. But up to now no structurally characterized Ag+ complexes with O,N,O coordinated N-acylhydrazones of salicylaldehyde were known. Therefore three Ag+ coordination compounds with functionally substituted N-acylhydrazones of salicylaldehyde were synthesized and characterized by X-ray diffraction, IR spectroscopy and thermogravimetric studies. In solutions the complexes were studied by 1H NMR and UV–Vis spectroscopy.
