Abstract

In the title compound, C27H30N4OS, the 3-(adamantan-1-yl)-4-amino-1H-1,2,4-triazole-5(4H)-thione unit and the O atom are each disordered over two sets of sites with refined site-occupancies of 0.7630 (13) and 0.2370 (13). The 1,2,4-triazole ring of the major component forms dihedral angles of 62.61 (17) and 61.93 (16)° with the benzene rings, while that of the minor component makes corresponding angles of 86.3 (4) and 79.1 (4)°. The dihedral angle between the benzene rings is 39.21 (16)°. The mol­ecular structure is stabilized by an intra­molecular C—H⋯N hydrogen bond, which generates an S(6) ring motif. In the crystal, mol­ecules are linked into inversion dimers by pairs of N—H⋯S hydrogen bonds.
