title: 5,6-Dimethyl-4-(thio-phen-2-yl)-1H-pyrazolo-[3,4-b]pyridin-3-amine.
abstract: In the title mol-ecule, C(12)H(12)N(4)S, the thio-phene ring is disordered over two orientations with a refined site-occupancy ratio of 0.777 (4):0.223 (4). The pyrazolo-pyridine ring system is essentially planar with an r.m.s. deviation of 0.0069 (3) Å and makes dihedral angles of 82.8 (2) and 72.6 (5)°, respectively, with the major and minor components of the thio-phene ring. In the crystal, mol-ecules are linked into a chain along the a axis by a pair of N-H⋯N(pyrazole) hydrogen bonds and a pair of N-H⋯N(pyridine) hydrogen bonds, both having a centrosymmetric R(2) (2)(8) graph-set motif. A C-H⋯π inter-action is also present.
