Project description:In the crystal structure of the title compound, C(11)H(10)N(2)O·H(2)O, the solvent water mol-ecule links the organic mol-ecules through O-H⋯O and O-H⋯N hydrogen bonds, forming chains that run diagonally across the bc face. These chains are connected to adjacent chains through weak C-H⋯O inter-actions, resulting in hydrogen-bonded sheets extending along the b and c axes. The sheets are connected along the a axis through π-π inter-actions, with centroid-centroid distances of 3.7571 (9) and 3.7231 (9) Å.

1-(4-Fluoro-phen-yl)-2-(1H-1,2,4-triazol-1-yl)ethanone hemihydrate.

Project description:In the title compound, C(10)H(8)FN(3)O·0.5H(2)O, the dihedral angle between the mean planes of the rings is 99.80 (4)°. The water mol-ecule lies on a twofold axis. Weak inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link one water mol-ecule with four phenyl-ethanone mol-ecules, while inter-molecular C-H⋯O hydrogen bonds involving the ketone group link phenyl-ethanone mol-ecules into layers parallel to (100).

1-[3,5-Bis(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

Project description:In the asymmetric unit of the title compound, C(17)H(14)F(2)N(2)O, there are three independent mol-ecules (A, B and C) which differ slightly in the relative orientations of the two fluoro-phenyl rings. In mol-ecules A and C one of the fluoro-phenyl rings is disordered over two positions, with occupancy ratios of 0.72 (2):0.28 (2) for mol-ecule A and 0.67 (2):0.33 (2) for mol-ecule C. The dihedral angle between the two fluoro-phenyl rings in the independent mol-ecules lie in the range 70.3 (3)-84.0 (3)°. In the crystal structure, the mol-ecules are linked via inter-molecular C-H⋯O and C-H⋯F hydrogen bonds and π⋯π stacking inter-actions [centroid-centroid distance = 3.7508 (13) Å], forming a three-dimensional network.

1-[3-(4-Fluoro-phen-yl)-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

Project description:In the title compound, C(17)H(15)FN(2)O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20 (5)°. In the crystal, a pair of C-H⋯O hydrogen bonds link neighbouring mol-ecules, forming an inversion dimer. The crystal structure is further consolidated by C-H⋯π inter-actions and by a π-π inter-action with a centroid-centroid distance of 3.7379 (6) Å.

Methyl 4-[5-(4-fluoro-phen-yl)-4-(pyridin-4-yl)-1H-imidazol-2-ylsulfan-yl]butanoate.

Project description:The title compound, C(19)H(18)FN(3)O(2)S, was synthesized in the course of studies on 2-alkyl-sufanylimidazoles as p38 mitogen-activated protein kinase inhibitors. The synthesis was achieved by nucleophilic substitution of 4-(4-fluoro-phen-yl)-5-(pyridin-4-yl)-1,3-dihydro-imidazole-2-thione with methyl 4-bromo-butanoate. The five-membered heterocycle makes dihedral angles of 32.4 (2) and 18.3 (2)° with the fluoro-phenyl and pyridinyl rings, respectively, indicating a low degree of conjugation between these rings. Intra-molecular C-H⋯N and inter-molecular N-H⋯N hydrogen bonds as well as C-H⋯π inter-actions seem to be effective in stabilization of the crystal structure.
