Structural study of di- and triorganotin(IV) dicarboxylates containing one double bond

Tri- and diorganotin(IV) dicarboxylates derived from trans-glutaconic acid and acetone 1,3-dicarboxylic acid were studied using NMR, IR and MS data and X-ray crystallography. Keto-enol tautomerism was observed in compounds derived from acetone 1,3-dicarboxylic acid.
