Bis(triorganylstannyl)chalcogenides (O, S, Se) have been studied by  119 Sn NMR in solution. In most cases the magnitude of the geminal coupling constants  2 J(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  2 J(SnSn) depending on X and on the bond angle SnXSn suggests that  2 J(SnOSn) &gt; 0 and  2 J(SnSSn),  2 J(SnSeSn) &lt;0. The X-ray diffraction study of bis(tribenzylstannyl)sulfide shows a bent arrangement (∢SnSSn 105.52(14)°) in contrast to the corresponding oxide.
