The title compound, C(16)H(17)NO(2), crystallizes with three crystallographically independent zwitterionic mol-ecules in the asymmetric unit which differ significantly in the orientations of the propyl side chains. The dihedral angles between the two benzene rings in the three mol-ecules are 6.17 (7), 6.75 (7) and 23.67 (7)°, respectively. In each independent mol-ecule, an intra-molecular N-H⋯O...

There are two nearly identical mol-ecules in the asymmetric unit of the title compound, C(7)H(7)NO. The mol-ecules are nearly planar (r.m.s. deviations of 0.025 and 0.017 Å) and oriented at a dihedral angle of 28.98 (3)°. The two mol-ecules are linked by a C-H⋯O hydrogen bond. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the c axis.

The asymmetric unit of the title compound, C(20)H(17)N(3), contains two crystallographically independent mol-ecules (A and B). In mol-ecule A, the two benzene rings form dihedral angles of 74.12 (7) and 7.83 (7)° with the pyridine ring, while in mol-ecule B these angles are 77.48 (7) and 21.50 (7)°. The seven-membered heterocyclic ring adopts a boat conformation in both mol-ecules. In the cryst...

The asymmetric unit of the title compound, [Ni(C(15)H(14)N(3)S(2))(2)], consists of two independent mol-ecules with similar configurations. Each Ni(2+) cation is coordinated in a cis-mode by two tridentate N,N',S-chelating Schiff base ligands, creating a distorted octa-hedron [the smallest angle being 77.57 (7)° and the widest being 168.97 (7)° for one mol-ecule, and 78.04 (7) and 167.55 (7)° f...

In the title compound, 2C(15)H(14)N(4)O(7)·2C(3)H(7)NO·H(2)O, the hydrazone mol-ecules are roughly planar, with the two benzene rings twisted slightly relative to each other by dihedral angle of 6.04 (11) and 7.75 (11)° in the two mol-ecules. The water mol-ecule is linked to the Schiff base mol-ecule by an O-H⋯O hydrogen bond. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, mol-ecul...

In the crystal structure of the title compound, C(9)H(7)BrN(4)OS·C(2)H(3)N, the mol-ecules are connected via N-H⋯O and N-H⋯S inter-actions into zigzag chains perpendicular to [001]. The mol-ecules in these chains are additionally linked to acetonitrile solvent mol-ecules through N-H⋯N hydrogen bonding. The mol-ecules are arranged in layers and are stacked in the direction of the c axis indicati...
