In the title compound, C20H14F3NS2, the seven-membered thia-zepine ring adopts a slightly distorted twist-boat conformation. The mean plane of the five-membered thio-phene ring fused to the thia-zepine ring is twisted by 32.3 (3) and 55.6 (4)° from the benzene and phenyl rings, respectively. In the crystal, inversion dimers linked by pairs of weak C-H⋯N inter-actions are observed.

The title compound, C(7)H(6)N(4)S, was synthesized by reacting pyridine-3-carboxylic acid and thio-semicarbazide. The dihedral angle between the planes of the thia-diazole and pyridine rings is 32.42 (14)°. In the crystal structure, inter-molecular N-H⋯N inter-actions link the mol-ecules into a three-dimensional network, forming R(2) (2)(8) ring motifs. π-π contacts between thia-diazole rings [...

In the title compound, C(24)H(28)N(2)O(4)S, the dihedral angle between the phenol ring and the thia-zole ring system is 10.6 (1)°, and the trimethoxy-phenyl group is approximately perpendicular to the thia-zole ring, the dihedral angle being 84.7 (2)°. There is a strong intra-molecular hydrogen-bonding inter-action between the Schiff base and the hydr-oxy group.

In the title compound, C14H11N5OS2, the triazolo-thia-diazole system is essentially planar (r.m.s. deviation = 0.002 Å) and makes dihedral angles of 6.33 (12) and 42.95 (14)° with the planes of the oxazole and phenyl rings, respectively. In the crystal, face-to-face π-π inter-actions are observed between the thia-diazole and oxazole rings [centroid-centroid distance = 3.4707 (18) Å], leading to...

In the title mol-ecule, C(24)H(20)N(2)O(2)S, the thia-zole and amide groups are essentially coplanar. The thia-zole ring forms dihedral angles of 61.62 (4) and 26.75 (5)° with the benzene rings of the methoxy-phenyl and methyl-phenyl groups, respectively, and 33.69 (6)° with the phenyl ring. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds, forming a three-dimensional n...

In the title compound, C(24)H(18)N(2)O(3)S, the benzofuran ring system (r.m.s. deviation = 0.010 Å) forms dihedral angles of 83.13 (17) and 8.92 (14)° with the benzene and thia-zole rings, respectively. The dihedral angle between the benzene and thia-zole rings is 84.51 (19)°. The mol-ecular structure features an intra-molecular C-H⋯O hydrogen bond, which closes an S(6) ring. There are no inter...

In the title compound, C12H9ClN2S, the imidazo[2,1-b]thia-zole fragment is planar (r.m.s. deviation = 0.003 Å), and the benzene ring is twisted slightly [by 5.65 (6)°] relative to this moiety. In the crystal, mol-ecules are linked by π-π stacking inter-actions into columns along [010]. The mol-ecules within the columns are arranged alternatively by their planar rotation of 180°. Thus, in the co...

Non-point source (NPS) pollution originating from agricultural development is the root cause of environmental pollution. Herein, we explore the integration of a NPS pollution model with novel spatial information technology to further understand the effects of enhanced crop development on local water resources. This study was based on land use, soil and precipitation data from studies conducted ...
