  ABSTRACT: In the title zwitterionic compound, C15H19NO2S, the six-membered heterocycle adopts a sofa conformation. The negative charge is delocalized along the carbonyl and enolate system on the ring and the positive charge is localized on the S atom. Two intermolecular C—H...O interactions help to establish the packing.

  ABSTRACT: In the crystal structure of the title compound, C26H22N4, the molecule is located on an inversion centre and shows an E configuration with respect to each C=N bond. The dihedral angle between the phenyl rings in the diphenylhydrazone group is 83.69 (11)°. These two rings make dihedral angles of 30.53 (15) and 84.53 (16)° with the central N—N=C—C=N—N dihydrazonoethane plane. Intermolecular C—H...π interactions are observed.

  ABSTRACT: In the title compound, C21H26N2O3, the morpholine ring has a chair conformation and the dihedral angle between the two phenyl rings is 59.0 (3)°. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds, generating a ribbon structure along the a axis. An intramolecular N—H...O contact is also present.
