Abstract

The syntheses and X-ray structures of novel heteroleptic thiolate/ dithiocarbamate derivatives (Et2NCS2)(2) (RS)(2)Sn (R = Cy, CH2CF3) have been examined and their thermal decompositions compared with those of selected tin(II) and tin(IV) dithiocarbamates. The heteroleptic species decompose to SnS by initial elimination of RSSR to afford (Et2NCS2)(2)Sn and subsequent loss of [Et2NC(S)](2)S. In contrast, (Et2NCS2)(4)Sn decomposes via [(Et2NCS2)(2)SnS](2), whose structure has been determined, and finally to SnS2 by sequential elimination of [Et2NC(S)](2)S. The two families of compounds, (R2NCS2)(4)Sn and (Et2NCS2)(2) (RS)(2)Sn, thus provide single- source materials for bulk SnS2 and SnS, respectively, by virtue of their differing decomposition pathways. Preliminary CVD experiments with (Et2NCS2)(2) (CyS)(2)Sn are also reported.
