2-{2-[4-(4-Fluoro­phen­yl)piperazin-1-yl]-2-oxoeth­yl}-6-(morpholin-4-yl)-4-phenyl­pyridazin-3(2H)-one

In the title compound, C26H28FN5O3, the morpholine ring adopts a chair conformation. The piperazine ring is puckered [Q T = 0.5437 (15) Å, θ = 8.89 (15) and ϕ = 357.2 (11)°]. The 1,6-dihydro­pyridazine ring makes dihedral angles of 28.03 (7) and 77.46 (7)° with the phenyl and benzene rings, respectively. In the crystal, mol­ecules are linked along the c axis by C—H⋯O inter­actions and are flattened parallel to the ac plane. C–H⋯π inter­actions also contribute to the stability of the structure
