Ethyl 7-chloro-1-cyclopropyl-6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylate
In the title compound, C(15)H(12)ClFN(2)O(5), mol-ecules are packed in the crystal lattice in a parallel fashion sustained by various C-H⋯O [C⋯O = 3.065 (5)-3.537 (5) Å] and C-H⋯Cl [3.431 (5)-3.735 (4) Å] inter-actions.

In the title compound, C10H4ClFO3, a chlorinated and fluorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0336 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.062 (2) Å] being for a benzene-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions [centroid-centroid distance between the benzene and py...

In the title compound, C10H4ClNO5, the non-H atoms of the 6-chloro-chromone unit are coplanar (r.m.s. deviation = 0.017 Å) with the largest deviation from the mean plane [0.031 (2) Å] being found for the C=O C atom. The nitro group (NO2) is inclined to the chromone unit mean plane by 13.3 (2) °. The formyl group is also twisted with respect to the attached ring [C-C-C-O torsion angles = 10.8 (4...

In the title compound, [Mg(C(16)H(17)FN(3)O(3))(2)(H(2)O)(2)]·6H(2)O, the Mg(2+) ion (site symmetry ) exhibits a distorted MgO(6) octa-hedral geometry defined by two O,O-bidentate 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazin-yl)-3-quinoline-carb-oxyl-ate (norf) anions and two water mol-ecules. In the crystal, O-H⋯O and O-H⋯N hydrogen bonds help to establish the packing.
