| 摘 要： | Three distannoxane dimers[(PhCH2)2(Cl)SnOSn(X)(CH2Ph)2]2(X=Cl,OMe,OEt)were prepared by the hydrolytic reaction of (PhCH2)2SnCl2 with sodium alkoxides.The compounds are assigned tetranuclear distannoxane structures in solid state.which contain the so-called ladder arrangement with a central planar Sn2O2 four-membered ring.The endo-and exo-cyclic Sn atoms are both five-coordinate,and have distorted trigonal bipyramidal geometries.A variety of hydrolyses of(PhCH2)2SnCl2 were performed and these dimers were characterized by IR,^1H NMR spectroscopy and X-ray diffraction analysis.

| Abstract: | Three distannoxane dimers [(PhCH 2) 2(Cl)SnOSn(X)(CH 2Ph) 2] 2 (X=Cl, OMe, OEt) were prepared by the hydrolytic reaction of (PhCH 2) 2SnCl 2 with sodium alkoxides. The compounds are assigned tetranuclear distannoxane structures in solid state, which contain the so called ladder arrangement with a central planar Sn 2O 2 four membered ring. The endo and exo cyclic Sn atoms are both five coordinate, and have distorted trigonal bipyramidal geometries. A variety of hydrolyses of (PhCH 2) 2SnCl 2 were performed and these dimers were characterized by IR, 1H NMR spectroscopy and X ray diffraction analysis. |
