2-Phenoxy-1,2,4-triazolo[1,5-a]quinazolin-5(4H)-one

Abstract

The triazoloquinazole ring system in the title compound, C 15H10N4O2 is approximately planar (r.m.s. deviation = 0.035 Å). The phenyl ring of the phenoxy substitutent is aligned at 59.3 (1)°with respect to this ring system. In the crystal, two molecules are linked about a center of inversion by a pair of N - H⋯O hydrogen bonds, generating a dimer.
