(E,E)-N,N'-Bis-(4-methoxy-benzyl-idene)cyclo-hexane-1,2-diamine.

ABSTRACT: In the title compound, C(22)H(26)N(2)O(2), the meth-oxy and the benzyl-idene groups are essentially coplanar, and the cyclo-hexane ring has a chair conformation. The two halves of the mol-ecule are related by a twofold rotation. The crystal structure is stabilized only by van der Waals inter-actions.

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

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.

rac-(E,E)-N,N'-Bis(2-chloro-benzyl-idene)cyclo-hexane-1,2-di-amine.

Project description:In the title racemic Schiff base ligand, C20H20Cl2N2, which was prepared by the condensation of 2-chloro-benzaldehyde and cyclo-hexane-1,2-di-amine, the cyclo-hexane ring adopts a chair conformation and the dihedral angle between the aromatic rings of the 2-chloro-phenyl substituent groups is 62.52?(8)°.

Project description:In the structure of the title compound, [Fe(2)(C(5)H(5))(2)(C(18)H(24)N(2))], the cyclo-hexane ring has a chair configuration and the two ferrocenemethyl-amino groups are bonded to it equatorially, as expected. The configuration of the two ferrocence nuclei may be due to intra-molecular N-H?N hydrogen bonding involving the two NH groups.

(1R*,2S*)-N,N'-Bis[(E)-1H-pyrrol-2-yl-methyl-idene]cyclo-hexane-1,2-diamine monohydrate.

Project description:The title compound, C16H20N4·H2O, was synthesized from cis-1,2-diamino-cyclo-hexane (a racemic mixture of the (1R,2S) and (1S,2R) enanti-omers). The compound crystallized with two mol-ecules (A and B) in the asymmetric unit with a single water solvent mol-ecule per Schiff base mol-ecule. Mol-ecules A and B have similar conformations as illustrated by the least-squares-fit with an r.m.s. deviation of 0.242 Å. The mol-ecules within the asymmetric unit are bridged by hydrogen bonds to the two water mol-ecules, resulting in a heterotetramer. The water mol-ecule acts as both a hydrogen-bond donor and acceptor. The pyrrole-imine units are not co-planar, making an angle of 73.9 (3)° and 76.9 (3)° in mol-ecules A and B, respectively.
