3-2-(9H-Carbazol-9-yl)eth­yl-4-phenyl-1H-1,2,4-triazole-5(4H)-thione di­methyl sulfoxide mono­solvate

摘要

In the title compound, C22H18N4SC2H6OS, the central triazolethione ring is inclined to the carbazole ring system by 13.97 (18) and to the phenyl ring by 66.4 (1). The lattice solvent, dimethyl sulfoxide, is strongly hydrogen bonded to the triazolethione ring. In the crystal, the main molecules form columns parallel to the a axis, with the solvent molecules located between the columns. C—HS hydrogen bonds and C—H(ring) interactions link adjacent columns. The crystal studied was refined as a two-component twin, with a fractional contribution to the minor domain of 0.0742 (14).
