Аннотация

The title compound C29H28N8O4, 1,1¢-(propane-1,3-diyl)bis(5-benzyl-7-methyl-1H-pyrazolo[3,4-d]××pyrimidine-4,6(5H,7H)-dione) is characterized by single crystal X-ray diffraction. It crystallizes in the centrosymmetric space group P , with two molecules in the unit cell. There is one formula unit in the asymmetric unit with a folded conformation due to arene interaction and an unusually large angle of 124° in the propylene linker. The crystal structure is stabilized due to the presence of π-π and C-H…O interactions.
