【 摘 要 】

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).
