N,N'-Bis(3-chloro-2-fluoro-benzyl-idene)ethane-1,2-diamine.

ABSTRACT: 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-molecular Cl?F [3.1747?(5)?Å] inter-actions, which are shorter than the sum of the van der Waals radii of these atoms. These inter-actions link neighbouring mol-ecules along the b axis. The crystal structure is further stabilized by ?-? inter-actions, with a centroid-centroid distance of 3.5244?(4)?Å.

Project description:The mol-ecule of the title Schiff base compound, C(16)H(12)Br(2)F(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bonds. 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-molecular Br?F inter-actions [3.2347?(16)?Å, which is shorter than the sum of the van der Waals radii of these atoms]. These inter-actions link neighbouring mol-ecules along the c axis. The crystal structure is further stabilized by inter-molecular C-H?N hydrogen bonds.

Project description: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 indicated by the dihedral angle between the two benzene rings of 3.74?(6)°. The inter-esting features of the crystal structure are weak inter-molecular Cl?N and F?F inter-actions, with distances of 2.9192?(11) and 3.2714?(10)?Å, respectively, which are shorter than the sum of the van der Waals radii of the relevent atoms. These inter-actions link neighbouring mol-ecules into dimers which are stacked down the b axis.

Project description:The mol-ecule of the title bidentate Schiff base ligand, C(18)H(20)N(2)O(2), has twofold crystallographic rotation symmetry, giving one half-mol-ecule per asymmetric unit. It adopts a twisted E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. The dihedral angle between the two benzene rings is 69.52?(5)°. The meth-oxy group is coplanar with the benzene ring, as indicated by the C-O-C-C torsion angle of -179.56?(8)°. In the unit cell, mol-ecules are linked together by inter-molecular C-H?O hydrogen bonds, forming chains along the a axis; these chains are further stacked down the b axis by both inter-molecular C-H?O and C-H?? inter-actions.

N,N'-Bis(2-iodo-benzyl-idene)ethane-1,2-diamine.

Project description:The mol-ecule of the title Schiff base compound, C(16)H(14)I(2)N(2), lies across a crystallographic inversion centre. An intra-molecular C-H?I hydrogen bond forms a five-membered ring, producing an S(5) ring motif. The C=N bond is coplanar with the benzene ring and adopts a trans configuration. 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 I?N [3.2096?(15)?Å] inter-action, which is significantly shorter than the sum of the van der Waals radii of these atoms. In the crystal structure, mol-ecules are linked into one-dimensional extended chains along the c axis and also into one-dimensional extended chains along the b axis through short inter-molecular I?N inter-actions, forming two-dimensional networks parallel to the bc plane.
