The reaction between 5-fluoroisatin and hydroxylamine hydrochloride in acidic ethanol yields the title compound, C8H5FN2O2, whose molecular structure matches the asymmetric unit and is nearly planar with an r.m.s. deviation for the mean plane through all non-H atoms of 0.0363 Å. In the crystal, the molecules are linked by N—H...N, N—H...O and O—H...O hydrogen-bonding interactions into a two-dimensional network along the (100) plane, forming rings withR22(8) andR12(5) graph-set motifs. The crystal packing also features weak π–π interactions along the [100] direction [centroid-to-centroid distance 3.9860 (5) Å]. Additionally, the Hirshfeld surface analysis indicates that the major contributio…
Crystal structure of (3E)-5-nitro-3-(2-phenylhydrazinylidene)-1H-indol-2(3H)-one

The reaction between 5-nitroisatin and phenylhydrazine in acidic ethanol yields the title compound, C14H10N4O3, whose molecular structure deviates slightly from a planar geometry (r.m.s. deviation = 0.065 Å for the mean plane through all non-H atoms). An intramolecular N—H...O hydrogen bond is present, forming a ring of graph-set motifS(6). In the crystal, molecules are linked by N—H...O and C—H...O hydrogen-bonding interactions into a two-dimensional network along (120), and rings of graph-set motifR22(8),R22(26) andR44(32) are observed. Additionally, a Hirshfeld surface analysis suggests that the molecules are stacked along [100] through C=O...Cginteractions and indicates that the most im…
Crystal structure of (2E)-3-[4-(dimethylamino)phenyl]-1-(thiophen-2-yl)prop-2-en-1-one

In the title chalcone-thiophene derivative, the dihedral angle between the aromatic and the thiophene rings is 11.4 (2)°. In the crystal, molecules are linked by C—H⋯O and C—H⋯S weak interactions along [100], forming rings of R22(8) graph-set motif, by C—H⋯O weak interactions along [010], forming C(6) chains, and by weak H(methyl–group)⋯Cg(thiophene ring) interactions into dimers; the crystal packing resembles a herringbone arrangement when viewed along [100]. A molecular docking calculation of the title compound with the neuraminidase enzyme was carried out.
