3-(p-Chlorophenyl)-4-phenyl-4,5-di-hydroisoxazole-5-spiro-2 '-1 ',2 ',3 ',4 '-tetrahydronaphthalen-1 '-one

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