N,N′-Bis(3-chloro-2-fluorobenzylidene)ethane-1,2-diamine
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 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].
متن کامل2-Chloro-12-phenyl-6,7,8,9,10,11-hexahydrocycloocta[b]quinoline
In the mol-ecule of the title compound, C(21)H(20)ClN, the quinoline group is nearly planar and is oriented at a dihedral angle of 77.21 (3)° with respect to the phenyl ring. The conformation of the cyclooctane ring is twist-boat. In the crystal structure, there are some weak π-π inter-actions [centroid-to-centroid distances of 3.7414 (11) and 3.8633 (12) Å] between the rings of the quinoline g...
متن کاملN,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.
متن کامل6-Chloro-N 2,N 4-di-p-tolyl-1,3,5-triazine-2,4-diamine dimethylformamide monosolvate
The title compound, C(17)H(16)ClN(5)·C(3)H(7)NO, was prepared by reaction of p-toluidine with 2,4,6-trichloro-1,3,5-triazine at room temperature. The dihedral angles between the triazine ring and the pendant rings are 3.61 (12) and 53.11 (12)°. An intra-molecular C-H⋯N inter-action occurs. The packing is stabilized by N-H⋯N and N-H⋯O hydrogen bonds and C-H⋯π and π-π [centroid-centroid distance ...
