(E)-4-(2-Chloro­benzyl­ideneamino)-3-(2-chloro­phen­yl)-1H-1,2,4-triazole-5(4H)-thione–(E)-1,5-bis­(2-chloro­benzyl­idene)thio­carbonohydrazide–methanol (1/1/1)

In the title compound, C(15)H(12)Cl(2)N(4)S·C(15)H(10)Cl(2)N(4)S·C(2)H(6)O, the two chloro­phenyl rings of the triazole derivative form dihedral angles of 65.7 (2) and 44.2 (2)° with the triazole ring. In the thio­carbonohydrazide derivative, the dihedral angle between the two chloro­phenyl rings is 5.4 (2)°. In the crystal, the triazole, thio­carbonohydrazide and methanol mol­ecules are linked by N—H⋯O, N—H⋯S and O—H⋯S hydrogen bonds, forming a hexa­meric unit.
