4-(3-Methoxy-phen-yl)-3-[2-(4-methoxy-phen-yl)eth-yl]-1H-1,2,4-triazol-5(4H)-one.

The asymmetric unit of the title compound, C(18)H(19)N(3)O(3), contains two crystallographically independent but similar mol-ecules. The triazole ring is oriented with respect to the benzene rings to form dihedral angles of 57.96†(6) and 7.01†(6)° in one mol-ecule, and 64.37†(5) and 10.73†(5)° in the other. The two independent mol-ecules are linked into a dimer by inter-molecular N-H⋯O hydrogen bonds.
