Abstract :
In the title compound, C32H28N2O, the imidazolidine and pyridine rings of the central hexahydroimidazo[1,2-a]pyridine ring system adopt envelope and screw-boat conformations, respectively. The molecule exhibits two weak intramolecular π–π interactions between phenyl rings. In the crystal, molecules are linked via pairs of C—H⋯ O hydrogen bonds, forming inversion dimers. The dimers are further linked by pairs of C—H⋯π interactions, forming infinite chains along the c-axis direction. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (73.4%), C⋯H/H⋯C (18.8%) and O⋯H/H⋯O (5.7%) contacts. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015[Spek, A. L. (2015). Acta Cryst. C71, 9-18.]). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported molecular weight and density.
