| Abstract: | The reaction of (NH4)2[WS4]
with 1-methylpiperazine results in the formation of 1-methylpiperazinediium
tetrasulfidotungstate monohydrate, in
good yield. (Me-pipH2)[WS4]·H2O has been
characterized by elemental analysis, IR, Raman and UV-vis spectra and its
crystal structure. The title compound crystallizes in the centrosymmetric
monoclinic space group P21/c
and its structure consists of a discrete, slightly distorted tetrahedral
tetrasulfidotungstate anion, 1-methylpiperazinediium cation and lattice water,
which are linked by five varieties of H-bonding interactions namely N-H···O,
N-H···S, O-H···S, C-H···O and
C-H···S. The lattice water links pairs of organic cations with pairs of [WS4]2-
anions via N-H···O, O-H···S, and C-H···O bonds, while the cations and anions
are linked via N-H···S, and C-H···S bonds. |
