3,5-Dimethyl-1-(2-pyridylcarbonyl)-5-[(2-pyridylcarbonyl)hydrazino]-2-pyrazoline methanol hemisolvate
The title compound, C(17)H(18)N(6)O(2)·0.5CH(3)OH, exists in the double keto form and adopts a highly puckered geometry, stabilized by intra-molecular N-H⋯O and N-H⋯N hydrogen bonds. Inter-molecular N-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid separation = 3.654 (1) Å] assemble the mol-ecules into chains running in the [111] direction. The methanol solvent mol-ecule is...

In the title mol-ecule, C(16)H(16)N(2)O(3), intra-molecular O-H⋯O hydrogen bonds influence the mol-ecular conformation. Inter-molecular O-H⋯O hydrogen bonds [O⋯O = 2.922 (2) Å] link the mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯O inter-actions assemble these dimers into layers parallel to the bc plane.

In the title compound, [Fe(C(5)H(5))(C(16)H(14)N(3)O(3))], the pyrazoline ring and the substituted cyclo-penta-dienyl ring are nearly coplanar, with a dihedral angle of 8.17 (2)°, while the nitro-substituted benzene ring is twisted out of the pyrazoline ring plane by 70.76 (1)°. The mol-ecules in the crystal structure are held together by three inter-molecular C-H⋯O hydrogen bonds. There is als...

The asymmetric unit of the title compound, C(15)H(13)BrN(2)O(3)·0.5CH(3)OH, contains two Schiff base mol-ecules and a methanol mol-ecule of crystallization. The dihedral angles between the benzene rings in the two mol-ecules are 23.8 (2) and 18.6 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional network.

The title methanol hemisolvated quinazolin-(3H)-one, C(16)H(16)N(4)O·0.5CH(3)OH, has an anilino substituent in the 2-position and an amino-ethyl substituent in the 3-position of the planar fused-ring system (r.m.s. deviation = 0.019 Å). The anilino N atom donates an intramolecular hydrogen bond to the amino-ethyl N atom. The mol-ecule and the solvent methanol mol-ecule are linked by N-H⋯N, N-H⋯...
