title: Syntheses and structural characterization of a monomeric tin(II) diamide and a novel chlorotin(II) amide trimer.
abstract: We have found that addition of a 2:1 ratio of the bulky ligand Li[N(mesityl)(SiMe(3))] to SnCl(2) yields Sn[N(mesityl)(SiMe(3))](2), which is found by X-ray crystallography to be monomeric in the solid state. Interestingly, the solid state structure of the stannylene exhibits a "minipocket" caused by the parallel arrangement of the phenyl rings. A 1:1 ratio of ligand to SnCl(2) affords the new chlorotin amide [Sn(mu-Cl)[N(mesityl)(SiMe(3))]](3), which adopts a unique trimeric structure in the solid state. The chairlike (Sn-Cl)(3) backbone shown here has not been seen previously in Sn-halide chemistry.
