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

摘要

The triazoloquinazole ring system in the title compound, C15H10N4O2 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.
