NOVEL HYDROXO BIDENTATE CARBOXYLATE BRIDGING IN DIORGANOTIN(IV) CARBOXYLATE COMPLEX - SYNTHESIS AND CRYSTAL-STRUCTURE OF -O,O'-BIS(TRICHLOROACETATO-O)-BIS[DIBUTYLTIN(IV)], SN-2(C4H9)(4)(O2CCCL3)(3)(OH)

The crystal structure determination of the title compound reveals that it appears to be entirely novel. It does not contain a stannoxane rin g, but both Sn atoms are held together by hydroxide and acetate bridge s, forming a six-membered ring. Both Sn atoms occupy distorted trigona l bipyramidal environments with one bidentate bridging trichloroacetat e group and one monodentate trichloroacetate group in axial positions, whilst the butyl groups and the bridging OH group lie in the equatori al plane.
