r-2,c-6-Bis(2-methoxyphenyl)-t-3,t-5-dimethylpiperidin-4-one acetic acid solvate

Abstract

In the title compound, C21H25NO3·C2H4O2, the piperidone ring adopts a chair conformation. The two methoxy groups are nearly coplanar with the aromatic rings to which they are attached. The dihedral angle between the two aromatic rings is 60.9 (2)°. There are two short intramolecular N—H...O contacts. The crystal packing is stabilized by intermolecular O—H...N and C—H...O interactions.
