N,N′-Bis(4-chloro-3-fluorobenzylidene)ethane-1,2-diamine
The asymmetric unit of the title Schiff base compound, C(16)H(12)Cl(2)F(2)N(2), contains one half of the centrosymmetric mol-ecule. Mol-ecules related by translation along the a axis form stacks with short inter-molecular C⋯C distances of 3.429 (3) Å. The crystal packing also exhibits short inter-molecular Cl⋯F contacts of 3.087 (1) Å.

The mol-ecule of the title centrosymmetric Schiff base compound, C(16)H(12)Cl(2)F(2)N(2), adopts an E configuration with respect to the azomethine C=N bond. The imino groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. An inter-esting feature of the crystal structure is the short inter-...

The complete mol-ecule of the title compound, C(24)H(20)Cl(2)N(4), is generated by a crystallographic inversion centre. A kink in the mol-ecule is evident [C-N-C-C torsion angle = -147.0 (3)°] owing to the twist in the central ethyl-ene bridge. Further, there is a small twist between the imine [N=C = 1.267 (3) Å] and quinoline residues [N-C-C-C = -12.4 (4)°]. In the crystal, a combination of π-...

In the title compound, C(11)H(15)ClN(4)O(2), the amino group is involved in intra- and inter-molecular N-H⋯O hydrogen bonds. The former contributes to the mol-ecular conformation, while the latter link the mol-ecules into centrosymmetric dimers. The crystal structure also exhibits weak inter-molecular C-H⋯O inter-actions.

The title mol-ecule, C(24)H(20)Cl(2)N(4), lies on an inversion center in an extended trans conformation. In the crystal, weak C-H⋯Cl inter-actions connect the mol-ecules into chains along [010].
