摘要：

The crystal structure of IPh2SnCH2CH2CO2Me: C16H17IO2Sn (10; X = I) has been determined, the tin atom adopts a distorted trigonal bipyramidal geometry, with iodine and the internal carbonyl oxygen in axial sites. The chelated structure of 10 (X = I) [nu(CO) 1684 cm-1] persists in such solvents as dichloromethane, chloroform, tetrahydrofuran and acetonitrile. Pyridine is able to compete with the intramolecular ester coordination in CH2Cl2 solution with the formation of unchelated IPh2Sn(py)CH2CH2CO2Me (11) [nu(CO) 1734 cm-1]; the formation constant of 11 is 0.07 +/- 0.01 1 mol-1 at 25-degrees-C.
