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