چکیده
In the title Schiff base, C21H14N4O4, the dihedral angle between the two nitro groups and the central benzene ring are 83.6 (5) and 2.6 (6)°. The anthracene ring system and the benzene ring make a dihedral angle of 0.7 (2)°. Intra-molecular N-H⋯O and C-H⋯N hydrogen bonds occur. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules, forming chains along the b-axis direction.

The mol-ecule of the title hydrazine derivative, C15H14N4O6, is essentially planar, the dihedral angle between the substituted benzene rings being 2.25 (9)°. The eth-oxy and hy-droxy groups are almost coplanar with their bound benzene ring [r.m.s. deviation = 0.0153 (2) Å for the ten non-H atoms]. Intra-molecular N-H⋯O and O-H⋯Oeth-oxy hydrogen bonds generate S(6) and S(5) ring motifs, respecti...

Intramolecular photoinduced electron transfer from a hydrazine unit to an aromatic group is studied by resonance Raman spectroscopy and electronic absorption spectroscopy. Substituted hydrazine functional groups have played an important role in studies of electron-transfer reactions, photoinduced intramolecular electron transfer, and of mixed valence. A prototypical compound, 2-tert-butyl-3-(an...

In the title compound, C(24)H(18)ClN(3)O(2)S, the dihedral angle between the benzene ring and the anthracene ring system is 41.10 (8)°. The thia-zine ring has a half-chair conformation and the Cl atom is in an axial orientation. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating C(8) chains along [100]. A C-H⋯N short contact occurs in the mol-ecule, generating an S(6) ring.
