title: Crystal structure of 1-methyl-4-methyl-sulfanyl-1H-pyrazolo-[3,4-d]pyrimidine.
abstract: In the title compound, C7H8N4S, the non-H atoms of the pyrazolo-[3,4-d]pyrimidine ring system and the methyl-sulfanyl group lie on a crystallographic mirror plane. In the crystal, mol-ecules are linked via a number of π-π inter-actions [centroid-centroid distances vary from 3.452 (7) to 3.6062 (8) Å], forming a three-dimensional structure.
