Four new diorganotin(IV), (R = Me, Bu), and triorganotin(IV), (R = Me, Ph), derivatives of the phosphomycin disodium saltantibiotic[(1R,2S)-1,2-epoxypropylphosphonate]Na2 have been synthesized and their solid state configuration studied by X-ray crystallography,FT-IR, Mossbauer, UV–Vis spectroscopies. The X-ray diffraction investigation, performed on the bis[trimethyltin(IV)]-phosphomycin, showed that the coordination geometry at all the Sn atoms is trigonal bipyramidal. The structure of the complex formsan unusual polymeric zig-zag planar network. The FT-IR and the 119Sn Mo¨ssbauer studies supported the formation of trigonal bipyramidal(Tbp) molecular structures, both in the diorganotin(IV) and triorganotin(IV) derivatives, even if, in the case of diorganotin(IV)derivatives, the tetrahedral structure cannot be a priori excluded. The PO32 group of phosphomycin coordinates the organotin(IV) centersoriginating a monodimensional polymeric network, as inferred by variable temperature 119Sn Mo¨ssbauer spectroscopy, used toinvestigate lattice dynamics of the bis-[trimethyltin(IV)]phosphomycin complex.
