Abstract

A family of tin(IV) bis(hexamethylsilylamide) complexes 29 have been synthesized by reaction of [Sn{N(SiMe3)2}2] (1) with the diphenyl dichalcogenanes Ph2E2 (E = S, Se, Te), the radical species TEMPO, or the group 16 elements to form the complexes [(PhE)2Sn{N(SiMe3)2}2] (24) and [(TEMPO)2Sn{N(SiMe3)2}2] (5), and [{(Me3Si)2N}2Sn(µ2-E)]2 (69) (E = S, 2 & 6; E = Se 3 & 7; E = Te, 4 & 9, E = O2, 9). The isolated tin complexes were characterized by elemental analysis, NMR spectroscopy, and the molecular structures of the complexes were determined by single crystal X-ray diffraction. Thermogravimetric analysis showed complexes 24 and 68 all to have residual masses close to those expected for the formation of the corresponding “SnE” systems. Complexes 24 and 68 were also assessed for their utility in the formation of nanoparticles. The materials obtained were characterized by powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and energy-dispersive X-ray analysis (EDX). Analysis showed formation of SnSe and SnTe from complexes 34 and 67, respectively.
