|Abstract:||The reaction of (NH<sub>4</sub>)<sub>2</sub>[WS<sub>4</sub>] with 1-methylpiperazine results in the formation of 1-methylpiperazinediium tetrasulfidotungstate monohydrate,<b style=""> </b>in good yield. (Me-pipH<sub>2</sub>)[WS<sub>4</sub>]·H<sub>2</sub>O 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 <i style="">P2<sub>1</sub>/c</i> 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 [WS<sub>4</sub>]<sup>2-</sup> 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.|
