Grinev, Vyacheslav S. published the artcileCrystal structures, packing features, Hirshfeld surface analyses and DFT calculations of hydrogen-bond energy of two homologous 8a-aryl-2,3,4,7,8,8a-hexahydropyrrolo[1,2-a]pyrimidin-6(1H)-ones, SDS of cas: 2051-95-8, the publication is Acta Crystallographica, Section C: Structural Chemistry (2020), 76(5), 483-489, database is CAplus and MEDLINE.
The crystal structures and packing features of two homologous Meyer’s bicyclic lactams with fused pyrrolidone and medium-sized perhydropyrimidine rings, namely, 8a-phenyl-2,3,4,7,8,8a-hexahydropyrrolo[1,2-a]pyrimidin-6(1H)-one, C13H16N2O (1), and 8a-(4-methylphenyl)-2,3,4,7,8,8a-hexahydropyrrolo[1,2-a]pyrimidin-6(1H)-one, C14H18N2O (2), were elucidated, and Hirshfeld surface plots were calculated and drawn for visualization and a deeper anal. of the intermol. noncovalent interactions. Mols. of 1 and 2 are weakly linked by intermol. C=O¡¤¡¤¡¤H-N hydrogen bonds into chains, which are in turn weakly linked by other C=O¡¤¡¤¡¤H-Car interactions. The steric volume of the substituent significantly affects the crystal packing pattern.
