The slow evaporation of analytical NMR samples resulted in the formation of crystals of (E)-2-({[4-(dimethylamino)phenyl]imino}methyl)-4-nitrophenol, C15H15N3O3, (I), and (E)-2-({[4-(diethylamino)phenyl]imino}methyl)-4-nitrophenol, C17H19N3O3, (II). Despite the small structural difference between these two N-salicylideneaniline derivatives, they show different space groups and diverse molecular packing. The molecules of both compounds are close to being planar due to an intramolecular O-H...N hydrogen bond. The 4-alkylamino-substituted benzene ring is inclined at an angle of 13.44 (19)° in (I) and 2.57 (8)° in (II) with respect to the 4-nitro-substituted phenol ring. Only very weak intermolecular [pi]-[pi] stacking and C-H...O interactions were found in these structures.

Crystal structure of trans-dichloridobis[N-(5,5-dimethyl-4,5-dihydro-3H-pyrrol-2-yl-κN)acetamide]palladium(II) dihydrate
Lasri, J.; Eltayeb, N. E.; Haukka, Matti; Babgi, B. A. (International Union of Crystallography, 2017)The title complex, [PdCl2(C8H14N2O)2]2H2O, was obtained by N–O bond cleavage of the oxadiazoline rings of the trans-[dichlorido-bis(2,5,5-trimethyl- 5,6,7,7a-tetrahydropyrrolo[1,2-b][1,2,4]oxadiazole-N1 )]palladium(II) ... -
Crystal structure of 5-{3-[2,6-dimethyl- 4-(5-methyl-1,2,4-oxadiazol-3-yl)phenoxy]propyl}- N-(11-hydroxyundecyl)isoxazole-3-carboxamide hemihydrate
Salorinne, Kirsi; Lahtinen, Tanja (International Union of Crystallography, 2015)The title compound, C29H42N4O5·0.5H2O, comprises four structural units. A flexible propyloxy unit in a gauche conformation, with a -C(H2)-C(H2)-C(H2)-O- torsion angle of -64.32 (18)°, connects an isoxazole ring and an ... -
Methyl 3',4',5'-trimethoxybiphenyl-4-carboxylate
Lahtinen, Manu; Nättinen, Kalle; Nummelin, Sami (International Union of Crystallography, 2013)In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16). In the crystal, the molecules are packed in an antiparallel fashion in layers along the a axis. In each layer, very weak C—HO ...
