Abstract

In the crystal structure of 1,3-bis(4,6-diisopropylsulfanyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)propane, C(25)H(36)N(8)S(4), the pairs of pyrazolo[3,4-d]pyrimidine rings in the molecule stack as a result of intramolecular pi-pi interactions between the heterocyclic rings. The crystal packing also exhibits an intermolecular C--H...pi interaction between one methyl group of an isopropyl group and a pyrazolo[3,4-d]pyrimidine ring.
