Sodium piperidine-1-carbodithio­ate dihydrate

The asymmetric unit of the title compound, Na(+)·C(6)H(10)NS(2) (−)·2H(2)O, is composed of a sodium cation, a piperidine­dithio­carbamate anion which exhibits positional disorder, and two lattice water mol­ecules. The atoms of the piperidine ring are divided over two sites with occupancy factors of 0.554 (6) and 0.446 (6). In the crystal, the sodium cation (coordination number of 6) and the piperidine­dithio­carbamate anion are linked, forming an infinite two-dimensional network extending parallel to (001). O—H⋯S hydrogen bonds, involving the lattice water mol­ecules, also aid in stabilizing the crystal sructure.
