2-{2-[4-(4-Fluoro-phenyl)piperazin-1-yl]-2-oxoethyl}-6-(morpholin-4-yl) -4-phenyl-pyridazin-3(2H)-one

Abstract

In the title compound, C26H28FN5O 3, the morpholine ring adopts a chair conformation. The piperazine ring is puckered [QT = 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.
