چکیده
The triazoloquinazole ring system in the title compound, C(15)H(10)N(4)O(2) is approximately planar (r.m.s. deviation = 0.035 Å). The phenyl ring of the phen-oxy substitutent is aligned at 59.3 (1)° with respect to this ring system. In the crystal, two mol-ecules are linked about a center of inversion by a pair of N-H⋯O hydrogen bonds, generating a dimer.
