(Z)-Ethyl 2-cyano-2-{2-[5,6-dimethyl-4-(thio-phen-2-yl)-1H-pyrazolo-[3,4-b]pyridin-3-yl]hydrazinylidene}acetate.

ABSTRACT: In the title compound, C(17)H(16)N(6)O(2)S, an intra-molecular N-H?O inter-action generates an S(6) ring. The pyridine ring makes a dihedral angle of 71.38?(11)° with the thio-phene ring. In the crystal, mol-ecules are linked by a pair of N-H?N hydrogen bonds, forming an inversion dimer. The dimers are stacked in columns along the b axis through weak inter-molecular C-H?N hydrogen bonds.

In the title compound, C(17)H(16)N(6)O(2)S, an intra-molecular N-H⋯O inter-action generates an S(6) ring. The pyridine ring makes a dihedral angle of 71.38 (11)° with the thio-phene ring. In the crystal, mol-ecules are linked by a pair of N-H⋯N hydrogen bonds, forming an inversion dimer. The dimers are stacked in columns along the b axis through weak inter-molecular C-H⋯N hydrogen bonds. ...[more]

Project description: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?? inter-action is also present.

Project description:In the title mol-ecule, C(15)H(17)N(3)O(4)S, the heterocyclic thia-zine ring adopts a twist-boat conformation, which differs from that in related compounds, with adjacent S and C atoms displaced by 0.981?(4) and 0.413?(5)?Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean plane of the benzene ring makes a dihedral angle of 23.43?(14)° with the mean plane of the pyrazole ring. In the crystal, mol-ecules are connected by weak C-H?O hydrogen bonds to form a three-dimensional network.
