Abstract
Sec-butylpropyldithiocarbamate compounds
of zinc(II), cadmium(II)
and stibium(III) have
been successfully synthesized by stoichiometric reaction of N-sec-butyl-N-propylamine,
carbon disulphide and ammonia with respective metal salts using the in situ
method with some modification. Gravimetric and elemental analysis data showed
that the ratio of metal to ligand were in agreement with the suggested
molecular formula, M[S2CNR1R2]n (M = Zn, Cd and Sb; R1 = -CH(CH3)(C2H5),
R2 = -C3H7;
n = 2 or 3). Infrared spectrum showed four
significant absorption peaks, ν(C-H), ν(CN), ν(CS) dan
ν(M-S) within the range. In 13C NMR spectrum showed a peak in the region
of 200.69 - 203.73 ppm, which was
attributed to the NCS2 group. The single crystal structures of
bis(N-sec-butyl-N- propyldithiocarbamato)zinc(II) and
bis(N-sec-butyl-N-propyldithiocarbamato)cadmium(II) have been determined. The
structure of both compounds is in monoclinic system with space group P21/n
and P21/c respectively. The bidentate behaviour of the
dithiocarbamate moieties exhibited in the crystal structures of both compounds.
