摘要
A series of new organotin(IV) dithiocarbamate compounds of type RnSn (S2CNR'R '')(4-n) (n = 2, 3; R = dimethyl, dibutyl, diphenyl, triphenyl and tert-butyl; R' = methyl, ethyl, benzyl; R '' = isopropyl, ethyl, ethanol) have been successfully synthesized. Elemental analysis showed that the percentage of the elements conformed to the general formula of these compounds. The important peaks of the infrared spectra for the stretching mode v(C=N), v(C=S), and v(Sn-S) for the compounds were observed in the area of 1440-1480 cm(-1), 940-1000 cm(-1), and 340-90 cm(-1), respectively. The C-13 NMR spectra showed the most important peak for (NCS2)-C-13 chemical shifts were observed in the range 190-210 ppm. X-ray single crystal studies for several structures of these compounds showed that the chelating mode of the dithiocarbamate groups to the central tin atoms were either bidentate or anisobidentate.
