SYNTHESIS AND SPECTROSCOPIC CHARACTERIZATION

The two title compounds have been synthesized, their IR and Mossbauer studies carried out. The structures are discrete and contain mono- and bidentate PhCO2 - , the environment around the tin (IV) centre being octahedral (in SnCl4 adduct), trapezoidal bipyramidal (in the SnBu2 residue containing derivative). A tetranuclear monomeric or an oligomeric structure is suggested in the tetranuclear SnBu2 residue containing derivative.
