Abstract

SnS, SnSe and SnTe are a potentially important semiconductor materials. Here, we described the application of chalcogenide Sn(IV) guanidinate precursors, for the production of tin(II) chalcogenide nano-crystals. Reaction of the stannylene (II) guanidinate complex [{Me2NC(NCy)2}2Sn] (1) with Ph2E2 (E = S, Se, Te), and CBr4 forms the Sn(IV) complexes [{Me2NC(NCy)2}2Sn(Ch-Ph)2] (2-4) and [{Me2NC(NCy)2}2SnBr2] (5) respectively. Complex 5 has been subsequently used for the synthesis of the corresponding Sn(IV) mono chalcogenide complexes, [{Me2NC(NCy)2}2Sn=E] (6-8) by the reaction of 5 with Li2E systems. Isolated tin complexes have characterized by elemental analysis, NMR spectroscopy, and the molecular structures of complexes 2-5 determined by single crystal X-ray diffraction. TG analysis showed complexes 2-4 and 6-8 all to have residual masses close to those expected for the formation of the corresponding 'SnE' systems. Complexes 6-8 were assessed for their utility in the formation of nano-crystalline materials. 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 7 and 8, respectively.
