Binuclear complexes of formula C5H15FeC5H4COOSn(CH=CH2)3 (I), C5H5FeC5H4COOSnPh3 (II) and Ph3GeCOOSnPh3 (III) have been prepared and characterized by IR spectra.The polymeric structure of solid C5H5FeC5H4COOSn(CH=CH2)3 has been established by X-ray crystallography.The crystals are monoclinic, space group P21/a, with a 15.105(5), b 10.030(4), c 11.402(4) Angstroem, and β 104.06(4) deg.In this compound the tin atoms are five-coordinate trigonal bipiramidal, with the vinyl groups equatorial and two apical oxygen atoms from bridging carboxylato groups.The resulting structure is a linear polymer with Sn-O bond lengths of 2.12 and 2.42 Angstroem.The spectra indicate that similar polymeric structure exist also for compounds II and III in the solid state, whereas an equilibrium monomer dimer seems to be present in CHCl3 solution for the compound III.
