چکیده
The main mol-ecule of the title methanol solvate, C(16)H(10)Cl(2)N(2)O·CH(3)OH, exists in the keto form and the C=O and N-H bonds are mutually cis in the crystal structure. The dihedral angle between the quinoline and benzene rings is 11.17 (3)°. A bifurcated intra-molecular N-H⋯(O,N) hydrogen bond is present as well as an O-H⋯O hydrogen bond. In the crystal, C-H⋯O inter-actions link the 3,5-dichloro-salicyl-idene-8-amino-quinoline and methanol mol-ecules.

In the title compound, C(16)H(10)Br(2)N(2)O·H(2)O, bifurcated intra-molecular N-H⋯(N,O) hydrogen bonding defines the essential planarity of the main mol-ecule: the dihedral angle between the quinoline and benzene rings is 7.53 (8)°. Inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds consolidate the crystal packing, which exhibits π-π inter-actions with a distance of 3.588 (1) Å between the cen...

In the title compound, C20H17NO3, the methyl-idene-cyclo-hexa-2,4-dienone moiety is approximately planar [maximum deviation = 0.0615 (10) Å] and is oriented at diherdral angles of 69.60 (7) and 1.69 (9)° to the phenyl and hy-droxy-benzene rings, respectively. The amino group links with the carbonyl O atom via an intra-molecular N-H⋯O hydrogen bond, forming an S(6) ring motif. In the crystal, th...

In the title Schiff base compound, C21H19NO3, the conformation about the C=C bond is Z. The N-H group and carbonyl O atom form an intra-molecular N-H⋯O hydrogen bond with an S(6) ring motif. The benz-yloxy ring and the 2-hy-droxy-5-methyl-phenyl ring are inclined to the central six-membered ring by 13.68 (9) and 9.13 (8)°, respectively, and to one another by 21.95 (9)°. In the crystal, mol-ecul...

The mol-ecule of the title compound, C(16)H(11)N(3)O(3), exists in the keto form and the C=O and N-H bonds are mutually cis in the crystal structure. There are two crystallographically independent mol-ecules per asymmetric unit with broadly similar structural data. The only noticeable difference between the two is the dihedral angles between the benzene and the quinoline rings: 1.04 (4) and 3.0...

The mol-ecular structure of the title titanium(IV) half-sandwich complex, [Ti(η5-C10H15)(η4-C21H19N)(C12H10N)], shows a three-legged piano-stool geometry at the central TiIV atom, comprising of one penta-methyl-cyclo-penta-dienyl ligand, one bidentate ketimine ligand in an η4-coordination mode and one monodentate di-phenyl-amide ligand. Except for van der Waals forces, there are no significant ...
