The set of six bis(triorganotin(IV)) esters of 4-ketopimelic acid was prepared. Their structures were studied using IR, NMR and X-ray crystallographic (cyclohexyl and ethyl derivatives) techniques both in solution and the solid state. Five of these compounds are polymeric in the solid state and depolymerise upon dissolving in non-coordinating and/or addition of coordinating solvent to monomeric species with four-coordinated tin atom or complexes with donor solvent with five-coordinated tin central atom. The tricyclohexyltin derivative is dimeric in the solid state and monomeric in solution.
