Ammonium piperidine-1-carbodithio­ate

Abstract

The title compound, NH₄ ⁺·C₆H₁₀NS₂ ⁻, is composed of an ammonium cation and a piperidine-1-carbodithio­ate anion which exhibits positional disorder. The atoms of the ring have a structural disorder and they are divided into two sites, with occupancy factors of 0.584 and 0.426.. In the crystal, the cation and anion are linked by N—H⋯S hydrogen bonds to form an infinite two-dimensional network.

Comment

The title compound is compossed of an ammonium cation and a piperidinedithiocarbamate anion. The crystal structures of similar compounds, for example pyrrolidinium 1-pyrrolidinecarbodithioate (Wahlberg, 1979), and β and α piperidinium 1-piperidinecarbodithionate (Wahlberg, 1980, 1981), have been reported.

The molecular structure of the title compound (Fig. 1) is built up of an ammonium cation and a disordered piperidinedithiocarbamate anion. The carbon atoms (C2-C6) are disordered, occupying two positions (A/B) with occupancies of 0.584 (8)/0.416 (8)

In the crystal the cation is linked to four piperidinedithiocarbamate anions via N-H···S hydrogen bonds (Table 1 and Fig. 2). These interactions lead to the formaion of an infinite two-dimensional network (Fig. 3), propagating in (001).

Experimental

The title compound was prepared by slow addition of 0.1 mol of CS₂ to a cold solution containing 0.2 mol of ammonia and 0.2 mol of piperidine dissolved in 30 ml of ethanol-water 1:1 (v/v) medium. The mixture was kept in an ice bath during the reaction. The solid obtained was recrystallized from ethanol-water 1:1 (v/v) and dried in a vacuum oven at 323 K for 8 h. Colourless single crystals, suitable for X-ray diffraction analysis, were obtained. On heating they sublimed and decomposed.

Refinement

The H-atom positions of the ammonium cation were located in a difference Fouier map and were freely refined: N-H = 0.78 (3) - 0.93 (3) Å. The C-bound H-atoms of the anion were included in calculated positions and treated as riding atoms: C-H = 0.97 Å, with U_iso(H) = 1.2U_eq(parent C-atom).
