摘要
In the crystal structure of 1,1'-(butane-1,4-diyl)bis(5-methyl-6methylthio-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-4-one), C18H22N8O2S2, (6), the pyrazolo[3,4-d]pyrimidine rings do not show any inter- or intramolecular stacking due to aromatic pi-pi interactions. There is a crystallographic inversion centre at the midpoint of the central C-C bond of the chain linking the two ring systems.
