4-Phenyl-1,2,4-tri­aza­spiro­[4.5]dec-1-ene-3-thione

In the title compound, C₁₃H₁₅N₃S, the 4,5-di­hydro-3H-1,2,4-triazole ring is nearly planar [maximum deviation = 0.020 (1) Å], while the cyclo­hexane ring adopts a chair conformation. The dihedral angle between the 4,5-di­hydro-3H-1,2,4-triazole ring and the phenyl ring is 74.68 (7)°. No specific inter­molecular inter­actions are discerned in the crystal packing.

(1Z,2E)-1-(3,4-Diphenyl-2,3-di­hydro-1,3-thia­zol-2-yl­idene)-2-(1-p-tolyl­ethyl­idene)hydrazine

In the title compound, C₂₄H₂₁N₃S, the thia­zole ring makes dihedral angles of 52.03 (6), 62.63 (6) and 12.35 (6)°, respectively, with the two phenyl rings and the benzene ring. In the crystal, weak C—H...π inter­actions occur between inversion-related mol­ecules.
