In the mol-ecule of the title compound, C(8)H(7)NO(4), the nitro group is approximately coplanar with the benzene ring [dihedral angle = 0.6 (1)°], while the dihedral angle between the methoxy-carbonyl group and the benzene ring is 8.8 (1)°. In the crystal structure, weak inter-molecular aromatic C-H⋯O(carbox-yl) and C-H⋯O(nitro) hydrogen-bonding inter-actions are present.

In the title compound, C12H13NO2, the five-membered ring has an envelope conformation; the disubstituted C atom lies out of the mean plane through the four other ring atoms (r.m.s. deviation = 0.0038 Å) by 0.1877 (18) Å. The plane of the phenyl substituent is practically perpendicular to that of the planar part of the five-membered ring, with a dihedral angle of 87.01 (5)°. In the crystal, mol-...

Two diferrous complexes, [Fe(2)(μ-SCH(2)CH(3))(3)(CO)(5)I] and [Fe(2)(μ-SCH(2)CH(2)CH(3))(3)(CO)(5)I] were synthesised via reaction of a monoiron carbonyl precursor, [Fe(CO)(4)I(2)], with ethanethiolate and propanethiolate, respectively. The complexes were fully characterised using spectroscopic techniques, for instance, FTIR and NMR. Their crystal structures were determined using single crysta...

Inclusion of the alpha,alpha'-bis(3-(1-methylimidazolium))-p-xylene dication in cucurbit[7]uril (CB[7], K(CB[7]) = (4.3 x 10(9) M(-1)), with C-H...O=C hydrogen bonding between the guest C(2)-protons and the carbonyl oxygens of the host portals, inhibits the H/D exchange for the C(2)-proton with k(OD) (25 degrees C, D2O) decreasing from 1.2 x 10(3) M(-1) s(-1) (pKa = 22.3) in the absence of CB[7...

Sodium circulation in Vibrio parahaemolyticus was investigated. We observed respiration-driven Na+ extrusion from cells by using a Na+ electrode. The Na+ extrusion was insensitive to a proton conductor, carbonyl cyanide m-chlorophenylhydrazone, and sensitive to a respiratory inhibitor, CN-. These results support the idea of the existence of a respiratory Na+ pump in V. parahaemolyticus. The res...

In the title compound, C(14)H(12)ClN(3)OS, the short exocyclic N-C bond lengths indicate resonance in the thiourea part of the mol-ecule. The title compound is stabilized by an intra-molecular N-H⋯N hydrogen bond, which results in the formation of a six-membered ring. In addition, it shows a synperiplanar conformation between the thio-carbonyl group and the pyridine group. Inter-molecular N-H⋯S...

The central Ni(II) atom in the title complex, [Ni(C(16)H(13)BrN(2)O(2))(C(5)H(5)N)], is in a square-planar trans-N(2)O(2) environment defined by the NO(2) donor atoms of the tridentate hydrazone ligand and the monodentate pyridine ligand. The pyridine mol-ecule forms a dihedral angle of 9.99 (11)° with the least-squares plane through the NiN(2)O(2) atoms.
