The cation and anion of the title salt, C14H18N3S2+·ClO4−, lie on a twofold rotation axis. The cation is a W-shaped entity with the aromatic rings at the ends; the ammonium NH2+ group is a hydrogen-bond donor to the pyridyl N atoms. The perchlorate ion has one O atom disordered over two sites in a 0.50:0.50 ratio.

Bis(2-chloroethyl)ammonium hydrochloride (8.92 g, 0.05 mol) in ethanol (100 ml) was added to a solution (353 K) of 2-mercaptopyridine (12.23 g, 0.11 mol) and potassium hydroxide (6.17 g, 0.11 mol) in ethanol (200 ml). The mixture was heated at 353 K for 8 h. The solvent was removed to yield a yellow oil; this was column chromatographed with ethly acetate/petroleum ether (3/5 v/v) as
yield 65%. 1H NMR (CDCl3, 400 MHz, p.p.m.): 3.316–3.349 (t, 4H), 2.959–2.992 (t, 4H), 6.924–6.960 (m, 2H), 7.154–7.173 (m, 2H), 7.416–7.459 (m, 2H), 8.382–8.393 (m, 2H).The title salt was obtained from the reaction of bis[2-(2-pyridylsulfanyl)ethyl]amine (0.5 mmol, 0.146 g) and copper perchlorate (0.5 mmol, 0.132 g) in ethanol. Colorless crystals were separated from the blue solution after three days. CH&N elemental analysis, calculated for C14H18O4N3S2Cl: C 42.91, H 4.63, N 10.72%; Found: C 42.73, H 4.35, N 11.02%.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.97 Å) and were included in the
in the riding model approximation, with Uiso(H) set to 1.2 times Ueq(C). The ammonium H-atom was similarly positioned [N—H 0.86 Å] and its temperature factor tied by a factor of 1.2.The perchlorate ion is disordered about the twofold rotation axis with respect to one O atom; two O atoms were assigned half-occupancy. The Cl—O distances were restrained to within 0.005 Å of each other, as were the O···O separations.
We are engaged in the study of metal complexes of di- and tri-(pyridylsulfanyl)alkylamines as such compounds owing to their flexible nature. We reported earlier the synthesis of tris[2-(2-pyridylsulfanyl)ethyl]amine, whose reaction with copper perchlorate gave instead tris[2-(2-pyridylsulfanyl)ethyl]ammonium perchlorate (An et al., 2010). The two-legged bis[2-(2-pyridylsulfanyl)ethyl]amine, in the present study, reacted with copper perchlorate to afford the corresponding ammonium perchlorate (Scheme and Fig. 1).
