摘要：
In the title compound, C7H8N4S, the methyl C atom is displaced by 1.232 (7) angstrom from the mean plane of the pyrazolo[3,4-d] pyrimidine ring system (r.m.s. deviation = 0.007 angstrom). The N-N-C-C-m (m = methyl) torsion angle is -60.3 (6)degrees. In the crystal, molecules are linked by N-H center dot center dot center dot S hydrogen bonds, generating [010] chains, which are reinforced by C-H center dot center dot center dot N interactions. The chains are cross-linked by weak C-H center dot center dot center dot S hydrogen bonds, generating (001) sheets.
