摘要：

The crowded organotin compound (PbMe2Si)3CSnMe2NCS is monomeric in the solid-state and contains tetracoordinate tin, the first tin isothiocyanate to be shown to do so. The related nitrate (PhMe2Si)3CSnMe2ONO2 is also monomeric, but there is a weak intramolecular interaction between the tin atom and one of the oxygen atoms of the NO2 group, making the tin quasi-pentacoordinate. The weak coordination appears, however, to have no significant effect on the disposition of the four full bonds around the tin, the geometry being markedly distorted from tetrahedral by steric interactions to a similar extent in both the nitrate and the isothiocyanate.
