The crystal structure of α,α’-dithiobisformamidinium dichloride, [SC(NH2)22Cl2, was determined and refined by Fourier and least-squares methods using 3-dimensional x-ray data collected with a single-crystal diffractometer (Cu Kα). The unit-cell parameters are: a 8.78(1), b 10.52-(1), c 19.69(1) Å; Z 8. Space group: Pbca. All the H atoms were located directly. The dithiobisformamidinium cation is in a general position and is formed by 2 planar thiourea groups which are slightly rotated with respect to the S-S bond [2.017-(2) Å] : (SCNN)ƛ(SSC) = 6.9 and 15.6°. The internal rotation angle around the S-S bond is 92.3°. Bond distances and angles in the thiourea groups agree with those found in thiourea and its derivatives A comparison is made of the corresponding dithiobis-formamidinium dibromide and diiodide. Packing is determined by a system of H bonds of the type N-H…Cl [3.132(5), 3.181(6), 3.120(5), 3.142(6), 3.145(6), 3.150(6) Å].
