2-Hydroxy-N′-[2-(6-methoxynaphthalen-2-yl)propanoyl]benzohydrazide
In the title compound, C21H20N2O4, the naphthalene ring system makes a dihedral angle of 84.5 (3)° with the benzene ring, and the –C(=O)–N(H)–N(H)–C(=O)– torsion angle is 70.7 (7)°, so that the molecule is twisted. An S(6) ring motif is formed via an intramolecular O—H⋯O hydrogen bond. In the crystal, molecules are linked by N—H⋯O and C–H⋯O hydrogen bonds into supramolecular layers in the ab plane

N-(2-Hydroxyphenyl)-4-methylbenzenesulfonamide
In the title compound, C13H13NO3S, the dihedral angle between the benzene rings is 64.15 (7)° and the C-S-N-C torsion angle is -57.18 (12)°. An intramolecular N-H...O hydrogen bond closes an S(5) ring. In the crystal, O-H...O hydrogen bonds link the molecules into C(8) chains propagating in [100]. Weak C-H...[pi] interactions are also observed
2-(4-Isobutylphenyl)-N′-[(3Z)-2-oxoindolin-3-ylidene]propanohydrazide
In the title compound, C21H23N3O2, the indolin-2-one group is essentially planar, with a maximum deviation of 0.016 (2) Å for the N atom, and makes a dihedral angle of 84.38 (14)° with the benzene ring. The =N—N(H)—C(=O)—C– torsion angle is 0.9 (3)°. In the crystal, molecules are linked into a three-dimensional network via N—H⋯O and C—H⋯O hydrogen bonds. In addition, a C—H⋯π interaction was observed
Bis(2-amino-5-benzyl-3-ethoxycarbonyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-5-ium) bis(4-methoxyphenyl)diphosphonate
N′-[(E)-2-chlorobenzylidene]-2-(6-methoxynaphthalen-2-yl) propanohydrazide
In the title compound, C21H19ClN2O2, the benzene ring and the naphthalene ring system are oriented at a dihedral angle of 65.24 (10)°. In the crystal, N—H⋯O, C—H⋯N and C—H⋯O hydrogen bonds link the molecules, forming chains along the b-axis direction. Further C—H⋯O hydrogen bonds link the chains, forming corrugated sheets lying parallel to (10-1)
