Multinuclear NMR and Moessbauer spectroscopy have been carried out for di- and triorganotin carboxylates derived from 3-(2-furanyl)-2-propenoic acid.Their spectroscopic characterization showed that triorganotin carboxylates are either 4-coordinate monomers or 5-coordinate polymers with bridging carboxylate groups.Although a polymeric structure is favoured for most compounds in the solid state, the solution studies indicated that they exist as monomeric 4-coordinate species in non-coordinating solvents.Diorganotin carboxylates of the general formulaR2Sn(OOCCHCHC4H3O)2 and dimeric 2 are penta-coordinate in noncoordinating solvents while in the solid phase intra- or intermolecular interactions are possible.Moreover, we report the fluxional behaviour of carboxylate anions in dimeric distannoxanes.The biological activity of these organotin carboxylates proved them to be powerful biocides.Keywords: Organotin; NMR; Biological activity; 3-(2-furanyl)-2-propenoic acid; Esters

The reaction of triphenyltin hydroxide with 2-furanyl, 2-furanvingl, 2-(5-terbutyl) furanyl, 2-(5-benzoyl) furanyl, 2-pyridinyl, 4-pyridinyl, 3-indolyl, 3-indolmethyl, 3-indolethyl and 3-indolpropyl carboxylates in 1:1 stoichiometry yields triphenyltin esters of heteroaromatic carboxylic acids Ph3SnO2CR. All compounds are characterized by elemental analysis, IR and 1H NMR. The crystal structure of the triphenyltin ester of 4-pyridinyl carboxylic acid (6) is determined by single crystal X-ray diffraction. In compound (6), the tin atom is rendered five-coordinate in a trigonal bipyramidal structure by coordinating with the 4-pyridinyl carboxlate group. The resulting structure is a linear polymer containing Sn-O bond lengths of 0.2160(5)-0.2166(5) nm and Sn-N bond lengths of 0.2512(6)-0.2612(6) nm.
