(2RS,5′RS)-3′,4′-Bis(4-chloro­phen­yl)-3,4-dihydro­spiro­[acridine-2,5′(4′H)-[1,2]oxazol]-1(2H)-one

The title compound, C₂₇H₁₈Cl₂N₂O₂, represents a racemic mixture of the corresponding R,R and S,S diastereomers. The isoxazoline ring adopts an envelope conformation with the spiro C atom deviating by 0.093 (2) Å from the rest of the ring. The six-membered keto-substituted carbocycle has a sofa conformation with the methyl­ene C atom adjacent to the spiro center deviating by 0.289 (2) Å from the mean plane of the remaining atoms. In the crystal, mol­ecules are linked via C—H...Cl inter­actions and C—Cl...O halogen bonds [2.958 (2) Å, 171.39 (7)°], which generate bifurcated R₂¹(6) ring motifs resulting in C₂¹[R₂¹(6)] chains running parallel to [010].
