3-(p-chlorophenyl)-4-phenyl-4,5-dihydroisoxazole-5-spiro-2'-1',2',3',4'-tetrahydronaphthalen-1'-one.

In the title compound, C24H18ClNO2, the phenyl ring and the tetralone moiety are approximately orthogonal to the isoxazoline ring. The isoxazoline ring adopts an envelope conformation, while the cyclohexenone ring of the tetralone moiety has an intermediate sofa/half-chair conformation. In this structure, one C--H...N intermolecular and two C--H...O intramolecular hydrogen bonds occur; the H.A distances are 2.60, and 2.35 and 2.57 A, respectively. The molecules are held together by an intermolecular C--H...N hydrogen bond, forming a one-dimensional chain along the [100] direction.
