1-(1<i>H</i>-1,2,3-Benzotriazol-1-yl)-2-(4-methoxyphenyl)ethanone

In the title compound, C(15)H(13)N(3)O(2), the dihedral angle between the benzotriazole ring system (r.m.s. deviation = 0.0124 Å) and the benzene ring is 76.21 (3)°. The meth-oxy C atom deviates from its benzene ring plane by 0.063 (2)Å. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(12) loops.
