N,N′-Bis[(E)-(5-chloro-2-thienyl)methylidene]ethane-1,2-diamine
The full mol-ecule of the title compound, C(12)H(10)Cl(2)N(2)S(2), is generated by the application of a centre of inversion. The thio-phene and imine residues are co-planar [the N-C-C-S torsion angle is -2.5 (4)°] and the conformation about the imine bond [1.268 (4) Å] is E. Supra-molecular arrays are formed in the bc plane via C-Cl⋯π inter-actions and these stack along the a axis.

The mol-ecule of the title Schiff base compound, C(18)H(12)Cl(2)F(6)N(2), adopts an E configuration with respect to the azomethine C=N bond. Intra-molecular C-H⋯F (× 2) and C-H⋯Cl (× 2) hydrogen bonds generate S(5) ring motifs. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the methyl-ene bridge, as...

In the title compound, C(11)H(11)ClN(4), the dihedral angle between the aromatic rings is 66.47 (8)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating C(5) chains propagating in [010]. Slipped aromatic π-π stacking between centrosymmetrically related pairs of pyrim-idine rings also occurs [centroid-centroid separation = 3.7634 (12)Å and slippage = 1.715 Å].

The asymmetric unit of the title compound, C(6)H(9)ClN(4), contains four independent mol-ecules (A, B, C and D). Their main difference is the torsion angles, ranging from 1.6 (5) to 5.9 (5)°, between the methyl group and the pyrimidine plane. A pair of inter-molecular N-H⋯N hydrogen bonds link mol-ecules A and C into a twisted dimer with a dihedral angle of 32.9 (1)° between the two pyrimidine ...

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.
