Abstract

The title compounds were prepared from aqueous alcoholic solutions by reaction of ammoniumdithiocarbamate with bismuth trichloride. NH(4)Bi(S(2)CNH(2))(4)center dot H(2)O crystallises in the monoclinic space group P2(1)/c (No. 14) with a = 8.4109(17), b = 13.198(3) and c = 16.678(3) angstrom, beta = 97.17(3)degrees and Bi(S(2)CNH(2))(3) crystallises in the triclinic space group P (1) over bar (No. 2) with a = 5.8951(5), b = 8.3026(7), c = 12.5030(10) angstrom, alpha = 103.460(10), beta = 95.080(10) and gamma = 91.330(10)degrees. The crystal structure of NH(4)Bi(S(2)CNH(2))(4)center dot H(2)O comprises isolated polyhedrons around bismuth (eightfold coordination) linked by hydrogen bonds originating from ammonium, the co-crystallised water and the dithiocarbamate. In the crystal structure of Bi(S(2)CNH(2))(3) exist dimeric aggregates comprising two distorted square antiprisms around bismuth, which are linked together by a common edge. They form infinite double chains with composition Bi(2)(S(2)CNH(2))(6)(infinity), which are bridged by N-H center dot center dot center dot S hydrogen bonds. Evaluation of differential thermal analysis data shows that Bi(2)S(3) develops in the temperature range between 125 and 150 degrees C, whereas mainly gaseous NH(3) and CS(2) are emitted during the decomposition reaction.
