چکیده
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)°. In the structure, there are two short intra-molecular methine C-H⋯Cl inter-actions [C⋯Cl = 3.066 (2) and 3.076 (3) Å], and in the crystal there are also weak inter-molecular aromatic C-H⋯Cl [3.464 (3), 3.553 (3) and 3.600 (3) Å] and Cl⋯Cl [3.557 (3) and 3.891 (3) Å] contacts.

The first FeIII atom in the solvated title compound, [Fe2Cl4O(C26H28N4)]·CHCl3, adopts a distorted six-coordinate octa-hedral geometry. It is coordinated by one chloride ligand, four N atoms from the (1R,2R)-N,N'-bis-[(quinolin-2-yl)methyl]cyclo-hexane-1,2-di-amine ligand, and a bridging oxido ligand attached to the second FeIII atom, which is also bonded to three chloride ions. A very weak int...

In the title complex, [Cu(ClO(4))(2)(C(7)H(12)N(2)O)(2)], the Cu(II) ion lies on a crystallographic inversion centre. The coordination sphere around Cu(II) ion can be described as tetragonally distorted octa-hedral with two perchlorate O atoms occupying the apical positions and four N atoms from two N(1)-(2-furyl-methyl)ethane-1,2-diamine ligands in the basal plane.

In the title compound, [FeCl(2)(C(34)H(36)N(4))], the Fe(II) ion is coordinated by two Cl atoms and by two N atoms from a (1R,2R)-N,N'-bis[2-(N-methyl-anilino)benzyl-idene]cyclo-hexane-1,2-diamine ligand in a distorted tetra-hedral geometry. The mol-ecule has approximate C(2) point symmetry. The dihedral angles between the phenyl and benzene rings on either side of the ligand are 64.56 (14) and...

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.
