Synthesis,characterization and IR investigation of three novel oxocentered,trinuclear of chromium,iron complexes containing unsaturated carboxylate bridging ligand

A series of novel oxo-centered trinuclear crystals,[M(2)M′O(C(3)H(3)O(2))6(H(2)O) (L)(2)](+)(M=Cr, M′= Cr,Fe;L=H(2)O,CH(3)OH) have been synthesized. The complexes werecharatrized by elemental analyses, Infrared and electronic spectroscopy and DSC analyses..These complexes containing unsaturated carboxylate bridging ligand thatcauses them to have potential scops for polymerization in the solid state by crosslinking of substituents. The trinuclear structure of complexes remains when the water molecules are replaced by methanol.
