Abstract
The novel metal complexes of ketoprofen (Hket)(1) with general formulae Mn(L)4(2), Co(L)4(3), Ni(L)4(4), and Zn(L)4(5) (where L= Hket, ket) were synthesized and characterized by elemental analysis, FTIR- spectroscopy and thermal decomposition techniques. All IR spectra revealed absorption bands related to the asymmetric (νas) and symmetric (νs) vibrations of carboxylate group. The Nakammoto criteria clearly indicate that this group is bonded in a bidentate-chelate mode. The thermal behavior of complexes was studied by TG, DTG methods under dynamic condition in air. Upon heating, all compounds decompose progressively to metal oxides, which are the final products of pyrolysis.
