3-Ethoxy-5-phenyl-1H-1,2,4-triazole

Hebishy, Ali M.; Elgemeie, Galal H.; Salama, Hagar T.; Jones, Peter G. GND

The title compound, C10H11N3O, crystallizes in the triclinic space group P[\overline{1}] with Z′ = 2. The two independent mol­ecules (A and B) differ in the orientation of the phenyl rings with respect to the plane of the triazine ring, with an interplanar angle of 11.45 (6)° in mol­ecule A and 19.71 (5)° in mol­ecule B, in the opposite sense. In the crystal, classical N—H⋯N hydrogen bonds cross-link the mol­ecules to form chains parallel to the b axis. Two additional `weak' C—H⋯O hydrogen bonds link the chains to form layers parallel to (101).
