The cation and anion of the title salt, C(14)H(18)N(3)S(2) (+)·ClO(4) (-), lie on a twofold rotation axis. The cation is a W-shaped entity with the aromatic rings at the ends; the ammonium NH(2) (+) 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.
