The organotin(IV) complexes, [(C4H4NS2CH2CO2)R2Sn(OMe)OSnR2]2 (R =Me1, n-Bu 2, Ph 3, PhCH2 4), have been synthesized and characterized by IR and 1H NMR spectroscopy. The structures of 1 and 2 have also been determined by X-ray crystallography. The structure analyses show that both complexes 1 and 2 feature a centrosymmetric core arranged as a ladder. Links between pairs of tin atoms are afforded by mi2-methoxo groups and each carboxylate anion coordinates an exocyclic tin atom exclusively, in the monodentatemode.Moreover, the packing of complexes 1 and2 are stabilized by the hydrogen bonding interactions.
