In the crystal, adjacent mol-ecules are linked via two pairs of inter-molecular N-H?S inter-actions, forming R 2 2(8) and R 2 2(10) ring motifs. Weak C-H?S inter-actions generate infinite chains along [001] and the structure is further consolidated by C-H?? bonds and aromatic ??? stacking inter-actions [distance between the centroids of the triazole rings = 3.2479 (7) Å].
