Crystal structure of (3E)-5-nitro-3-(2-phenylhydrazinylidene)-1H-indol-2(3H)-one
2017
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 5-(4-tert-butoxyphenyl)-3-(4-n-octyloxyphenyl)-4,5-dihydroisoxazole
2019
The molecule of the title compound, C27H37NO3, was prepared by [3 + 2] 1,3-dipolar cycloaddition of 4-n-octylphenylnitrile oxide and 4-tert-butoxystyrene, the latter compound being a very useful intermediate to the synthesis of liquid-crystalline materials. In the molecule, the benzene rings of the n-octyloxyphenyl and tert-butoxyphenyl groups form dihedral angles of 2.83 (7) and 85.49 (3)°, respectively, with the mean plane of the isoxazoline ring. In the crystal, molecules are linked by weak C—H...O hydrogen interactions into chains running parallel to the b axis.
