In the title compound, [Pb(2)(C(7)H(4)FO(2))(4)(H(2)O)(2)](n), one Pb(II) atom is coordinated by seven O atoms and one F atom from five 2-fluoro-benzoate ligands, and the other Pb(II) atom is coordinated by five O atoms from four 2-fluoro-benzoate ligands and three water mol-ecules, resulting in distorted PbO(7)F and PbO(8) polyhedra. The 2-fluoro-benzoate ligands bridge Pb atoms, giving rise t...

In the complex cation, the Ag(I) ion is coordinated by two C atoms; the two imidazolium rings are orientated at a dihedral angle of 8.14 (14)°. In the 1-benzyl-3-methyl-imidazolium units, th...

Herpes simplex and vaccinia viruses and adenovirus types 1, 2, 5, and 7 were tested by plaque suppression methods for sensitivity to halogenated deoxyuridines (5-iodo-, 5-bromo-, 5-chloro-, and 5-fluoro-), cytosine arabinoside, isatin-beta-thiosemicarbazone, and N-methylisatin-beta-thiosemicarbazone. After incubation for 12 days in HeLa cell cultures, vaccinia virus plaques were still readily s...

12-Fluoro-5-methylchrysene, which has a fluorine atom at a peri position, is less carcinogenic toward mouse skin than is 5-methylchrysene. To determine the basis for this observation, we identified metabolites of 12-fluoro-5-methylchrysene formed by rat liver in vitro, and used these as standards to study the metabolism of [3H]-12-fluoro-5-methylchrysene in mouse liver in vitro and in mouse epi...

The structure of the title compound, [Ni(C13H9FNO)2(C5H5N)2], consists of an Ni(II) atom on a crystallographic center of symmetry, octa-hedrally bonded through both the N and O atoms to two 2-[(2-fluoro-phen-yl)imino-meth-yl]phenolate (L) ligands, as well as two pyridine ligands. The F atoms of L are disordered over two positions related by a 180° rotation of the fluoro-phenyl group around its ...

In the crystal structure of the title compound, C(15)H(11)FN(2), the pyrrole ring makes dihedral angles of 33.19 (9) and 36.33 (10)° with the pyridine and 4-fluoro-phenyl rings, respectively. The pyridine ring makes a dihedral angle of 46.59 (9)° with the 4-fluoro-phenyl ring. In the crystal structure, an N-H⋯N hydrogen bond joins the mol-ecules into chains.

In the title compound, C12H15FN2O2S, the mol-ecule adopts a cis configuration of the fluoro-benzoyl group with respect to the thiono group about their C-N bond. The dihedral angle between the fluoro-benzoyl group and the thio-urea N2CS fragment is 69.60 (11)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, mol-ecules form chains along the b-axis direction via O-H⋯S and C-H⋯O hyd...
