L,L'-Diacetylferrocenebis(5-Phenyl-L,3-Oxazol-2-Ylcarbonyl)Hydrazone and Its Complexes

Abstract

A new heterocyclic ferrocene derivative, 1,1′-diacetylferrocenebis(5-phenyl-1,3-oxazol-2-ylcarbonyl)hydrazone (H₂Dfoh) and its coordination complexes, [M₂(Dfoh)-(OAc)₂]-nH₂O [(M = Cu(H), Ni(H), Co(H), Cd(H), Pb(H), Mn(H)], were prepared by reacting H₂Dfoh with the metal acetates and were characterized by elemental analyses, molar conductivities, IR, ¹H NMR, UV spectra and thermal analyses. H₂Dfoh appears to act as a bidentate ligand, coordinating to two metal atoms through the azomethine nitrogen and enolic oxygen atoms. OAc” coordinates to the metals as a symmetric bidentate ligand.
