摘要

The crystal structure of the title compound, C25H24N2O2, at 173 K has monoclinic (C2/c) symmetry. The mol­ecule is located on a crystallographic twofold rotation axis with only half a mol­ecule in the asymmetric unit. The imidazolidine ring adopts a twist conformation, with a twist about the ring C—C bond. The crystal structure shows the anti­clinal disposition of the two (2-hy­droxy­naphthalen-1-yl)methyl substituents of the imidazolidine ring. The structure displays two intra­molecular O—H⋯N hydrogen bonds, each forming an S(6) ring motif.
