In the crystal structures of 4,6-dimethylthio-1-[3-(4,6-dimethylthio-2H-pyrazolo[3,4-d]pyrimidin-2-yl)propyl]-1H-pyrazolo[3,4-d]pyrimidine, C17H20N8S4, and 1-[4-(4-methoxy-6-methylthio-1H-pyrazolo[3,4-d]pyrimidin-1-yl)butyl]-5-methyl-6-methylthio-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-4-one, C18H22N8O2S2, only intermolecular stacking due to aromatic π–π interactions between pyrazolo[3,4-d]pyrimidinerings is present.
