In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluoro-phenyl and benzoyl-phenyl rings, respectively. The dihedral...

Refluxing a mixture of 1,10-phenanthroline, (4-fluoro-phen-yl)thio-urea and cadmium(II) chloride did not produce the expected mixed-ligand complex but formed a co-crystal of the two ligands, C12H8N2·C7H7FN2S. The asymmetric unit consists of two pairs of the co-crystal mol-ecules. In each (4-fluoro-phen-yl)thio-urea mol-ecule, the planes of the N2CS thio-urea units are almost perpendicular to th...

In the title compound, C(24)H(12)BrF(2)NO(4), synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 4-fluoro-benzoyl chloride, the two p-fluoro-phenyl rings are inclined at 73.9 (1) and 73.6 (1)° to the naphthoquinone ring system. The two imido carbonyl O atoms are anti to each other, while the fluoro-phenyl rings are located opposite each other, connected to the imide group in a funnel-like ...

Fluoro-Deoxy-Glucose Positron Emission Tomography/Computerized Tomography scan is a very useful method in the diagnosis and follow-up of gastrointestinal malignancies, although it may cause confusion in differential diagnosis.We present a 48-year-old man admitted with a right lower quadrant mass. Upon an unyielding colonoscopy due to inability to pass beyond the hepatic flexure, a Fluoro-Deoxy-...

In the title compound, C(19)H(19)FN(2)O(2)S, the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the plane of the fluoro-phenyl ring forms a dihedral angle of 41.5 (1)° with respect to the carbazole mean plane. The crystal structure is segregated into layers containing the carbazole units and fluoro-phenyl rings in alternate (200) planes. The carbazole ...

The title compound, C21H11ClF6N2O3 (systematic name: 1-{4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-fluorophenyl}-3-(2,6-di-fluoro-benzo-yl)urea), is a benzoyl-urea pesticide. The dihedral angles between the central fluoro-benzene ring and the terminal di-fluoro-phenyl ring and chloro-phenyl ring system are 62.15 (5) and 88.03 (5)°, respectively. In the crystal, N-H⋯O hydrogen bonds link adjacent...

The structure of the NAD-dependent oxidoreductase UDP-galactose-4'-epimerase from Trypanosoma brucei in complex with cofactor and the substrate analogue UDP-4-deoxy-4-fluoro-alpha-D-galactose has been determined using diffraction data to 2.7 A resolution. Despite the high level of sequence and structure conservation between the trypanosomatid enzyme and those from humans, yeast and bacteria, th...

In the title mol-ecule, C(17)H(10)F(3)N(3)O, the C=C bond connecting the triazole ring and 4-fluoro-phenyl groups adopts a Z conformation. The triazole ring forms dihedral angles of 15.3 (1) and 63.5 (1)°, with the 2,4-difluoro-substituted and 4-fluoro-substituted benzene rings, respectively. The dihedral angle between the two benzene rings is 51.8 (1)°.

In the title compound, C(20)H(17)F(2)NO(4)S(2), the dihedral angles between the o-xylene ring and the fluoro-benzene rings are 31.7 (1) and 32.8 (1)°, and the dihedral angle between the fluoro-benzene rings is 50.9 (1)°. The C-N-S-C torsion angles are 76.7 (2) and 101.8 (2)°. In the crystal, mol-ecules are connected by C-H⋯O inter-actions into sheets in the ab plane.

In the title compound, C(21)H(16)F(2)N(2), the dihedral angle between the fluoro-phenyl groups is 66.34 (8)°, and the dihedral angle between the envelope-configured pyrazole group (N/N/C/C/C) and the benzene ring is 11.50 (9)°. The dihedral angles between the benzene and the two fluoro-substituted phenyl groups are 77.7 (6) and 16.7 (5)°. Weak C-H⋯π interactions contribute to the stability of t...
