One triphenyl, one tributyl, and two dibutyl esters of p-methoxy trans-cinnamic acid have been synthesized and characterized by IR, NMR (1H, 13C, 119Sn) and 119Sn Moessbauer spectral data. Spectroscopic data suggest that the carboxy-dibutyl distannoxane adopts a ladder structure containing five-coordinate tin atoms, while the dibutyltin bis(cinnamate) ester has a distorted six-coordinate trans-R2SnO4 structure. The tributyltin ester is a five-coordinated polymer in the solid state and is a four-coordinate monomer in solution. The corresponding triphenyltin ester is four-coordinate in the solid and in solution.
