The crystal structure of the title compound, C25H24N2O2, at 173 K has monoclinic (C2/c) symmetry. The mol-ecule is located on a crystallographic twofold rotation axis with only half a mol-ecule 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 anti-clinal disposition of the two (2-hy-droxy-naphthalen-1-yl)methyl substituents of the imidazolidine ring. The structure displays two intra-molecular O-H⋯N hydrogen bonds, each forming an S(6) ring motif.
标题化合物C25H24N2O2在173 K时具有单斜（C2/c）对称性。分子位于一个晶体学二重旋转轴上，不对称单元中只有半个分子。咪唑烷环呈扭曲构象，围绕环C-C键发生扭曲。晶体结构显示咪唑烷环的两个（2-羟基萘-1-基）甲基取代基呈反式排列。该结构呈现出两个分子内O-H⋯N氢键，每个氢键形成一个S(6)环模式。
