SYNTHESIS AND STRUCTURES OF INTRAMOLECULARLY HEXACOORDINATED ORGANOTIN CHLORIDES CONTAINING THE (3-(2-METHOXY)ETHOXY)PROPYL MOIETY

Two water-soluble organotin compounds, (3-(2-methoxy)ethoxy)propyltin trichloride, 1, and bis (3-(2-methoxy)ethoxy)propyltin dichloride, 2, were synthesized and characterized by H-1, C-13 and Sn-119 NMR spectro scopy and by X-ray diffraction. In both cases, the geometry at the tin atom is that of a distorted cis-octahedron, which is preserved for bo th compounds in CDCl3 solution. A detailed solution structure is propo sed for 1 from 1D H-1-Sn-119 HMQC NMR experiments. (C) 1997 Elsevier S cience S.A.
