A series of tin unsymmetric dithiocarbamate complexes have been made from metathesis reaction of [CH3(C4H9)NSC2]Li and RnSnCl4-n; [RnSn(S2CN(C4H9)CH3) 4-n] [n = 3, R = Me (1), Bu (2), Ph (3); n = 2, R = Me (4), Bu (5), Ph (6); n = 1, R = Me (7), Bu (8), Ph (9)]. The complexes were characterised by microanalysis, 13C, 1H and 119Sn NMR, M?ssbauer and, in the case of 3, by X-ray diffraction, which revealed one short Sn-S [2.4631(9) ?] and one long Sn-S interaction [3.084(1) ?] indicative of a weakly chelating dithiocarbamate ligand. Atmospheric pressure chemical vapour deposition using 1 and 8 with H2S at 350-550 °C produced SnS and Sn2S3 films on glass substrates. The tin sulfides were analysed by Raman, EDAX, SEM and band gap measurements. Growth rates were of the order of 150 nm min-1.
