Source of material
The compound was obtained commercially as “ammonium pyrrolidine dithiocarbamate” (APDC) from Hopkin & Williams Ltd. Crystals suitable for the diffraction study were obtained directly from the crystalline reaction product. An explanation for the presence of the title compound in the provided product is not at hand.
Experimental details
Carbon-bound H atoms were placed in calculated positions (C–H 0.99 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C).

Discussion
Carboxylic acids have been used as ligands in coordination chemistry for many decades. Especially for acetic acid, interesting bonding patterns have been realized for transition metals due to its ability to act as bridging ligand, e.g. for chromium(II)acetate where the presence of a metal-metal quadruple bond has been established on grounds of diffraction studies conducted on single crystals [1–3]. Considerably less work has been conducted for dithiocarboxylic acids in general as well as dithioacetic acid in particular. For the latter, only few compounds whose molecular structure has been elucidated on grounds of diffraction studies based in single crystals have been reported, among others, for platinum [4] and gold [5]. At the beginning of a study about the coordination behaviour of dithiocarboxylic acids bearing heterocyclic substituents, ammonium pyrrolidine dithiocarbamate was chosen as a starting point. As the spectral and analytical properties of the commercially-obtained compound deviated significantly from the expected ones, a structural analysis of the crystalline material was conducted. The results showed the presence of an unexpected compound. The title compound is the C2 symmetric dithioamide derived from pyrrolidine and thiophosgene. The two heterocycles connect to the central C=S unit via their nitrogen atoms. The C–S bond is measured at 1.6928(11) Å while the two C–N bonds towards the central carbon atom are found at 1.3467(14) Å and 1.3575(14) Å. The latter values are in good agreement with the most common ones reported for other dithioamide compounds whose metrical parameters have been deposited with the Cambridge Structural Database [6] and are indicative of amide-type resonance. A puckering analysis of the five-membered rings according to Cremer & Pople [7] shows the adoption of 4T3 conformations in both cases (C13TC12 and C23TC22, respectively) [8]. The least-squares planes as defined by the non-hydrogen atoms of both rings enclose an angle of 62.87(4)°. In the crystal, C–H⋯S contacts whose range falls below the sum of van-der-Waals radii can be observed [9]. These are established by one hydrogen atom on one of the methylene groups directly bonded to the nitrogen atom each in both cycles. In terms of graph-set analysis [10, 11], the descriptor for these contacts is C11(5)C11(5) on the unary level. In total, the molecules are connected to planes perpendicular to the crystallographic c axis.
