Ethyl 3-amino-5-anilino-4-cyano-thio-phene-2-carboxyl-ate.

ABSTRACT: In the title compound, C14H13N3O2S, the dihedral angle between the thio-phene and phenyl rings is 24.95?(8)°. The mol-ecular structure is consolidated by intra-molecular N-H?O and C-H?S inter-actions. The crystal structure features N-H?N and N-H?O hydrogen bonds forming centrosymmetric R 2 (2)(12) dimers, which are linked into a two-dimensional network parallel to (011) with an S(6)R 2 (2) S(6) motif. In addition, ?-? stacking inter-actions [centroid-centroid distance = 3.7013?(12)?Å] occur between the thio-phene and phenyl rings of adjacent mol-ecules.

Ethyl 2-amino-4,5-dimethyl-thio-phene-3-carboxyl-ate.

Project description:In the title compound, C(9)H(13)NO(2)S, the mean planes of thio-phene ring [maximum deviation = 0.0042 (10) Å] and eth-oxy-carbonyl group [0.0242 (15) Å] are almost coplanar [dihedral angle between them = 0.68 (11)°]. The H atoms of the two methyl groups attached to the thio-phene ring are each disordered over two orientations with site-occupancy ratios of 0.77 (4):0.23 (4) and 0.84 (4):0.16 (4). An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into an infinite wave-like chain running parallel to the b-axis direction. The crystal structure also features C-H⋯π inter-actions.

Project description:In the title thio-phene derivative, C13H18N2O3S, the dihedral angles between the thio-phene ring and the [(di-methyl-amino)-methyl-idene]amino side chain (r.m.s. deviation = 0.009 Å) and the -CO2 ester group are 3.01 (16) and 59.9 (3)°, respectively.

Project description:In the title salt, C6H10N3O2 (+)·C5H3O2S(-), the 2-amino-4,6-di-meth-oxy-pyrimidinium cation inter-acts with the carboxyl-ate group of the thio-phene-2-carboxyl-ate anion through a pair of N-H⋯O hydrogen bonds, forming an R 2 (2)(8) ring motif.
