Synthesis, crystal and molecular structure of 3‐phenyl‐5‐p‐tolyl‐4‐(3,4,5‐trimetoxybenzilideneamino)‐4H‐1,2,4‐triazole

A new 1,2,4‐triazole derivative, 3‐phenyl‐5‐p‐tolyl‐4‐(3,4,5‐trimetoxy benzilideneamino)‐4H‐1,2,4‐triazole, C 25 H 24 N 4 O 3 (1), has been prepared by the reaction of 4‐amino3‐phenyl‐5‐p‐tolyl‐4H‐1,2,4‐triazole and 3,4,5‐trimetoxybenzaldehyde and structurally characterized by single crystal X‐ray diffraction. Compound (1) crystallizes in the monoclinic space group P2 1 /c with a = 12.4336(11), b = 12.5860(11), c = 14.3944(14)Å, β = 94.417(7)°, Z = 4, V = 1.267 Å 3 . In the solid state, the molecules of (I) are discrete and not planar, comprising a twisted four‐ring system. The molecules are held together with van der Waal's interactions.
