title: 2-Benzyl-6-benz-yloxypyridazin-3(2H)-one.
abstract: In the title compound, C(18)H(16)N(2)O(2), the central pyridazine ring forms dihedral angles of 77.08 (5)° and 84.62 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 68.18 (4)°. A very weak intra-molecular C-H⋯N hydrogen bond and an intra-molecular C-H⋯π inter-action occur. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and weak C-H⋯π and π-π stacking inter-actions [centroid-centroid distance = 3.6867 (10) Å].
