Bis(triorganylstannyl)chalcogenides (O, S, Se) have been studied by 119Sn NMR in solution. In most cases the magnitude of the geminal coupling constants 2J(SnSn) are indicative of a bent arrangement SnXSn (X = O, S, Se). The exception is bis(tri-tert-butylstannyl)oxide for which the linear structure S n - O - S n as determined by X-ray diffraction in the solid state is preserved in solution. The trend of the coupling constants 2J(SnSn) depending on X and on the bond angle SnXSn suggests that 2J(SnOSn) > 0 and 2J(SnSSn), 2J(SnSeSn) <0. The X-ray diffraction study of bis(tribenzylstannyl)sulfide shows a bent arrangement (∢SnSSn 105.52(14)°) in contrast to the corresponding oxide.
