چکیده
The title mononuclear complex, [Zr(C(20)H(20)Cl(4)N(2)O(2))(2)], was obtained by allowing hexane to diffuse into a diethyl ether solution of zirconium(IV) sec-butoxide and the enanti-o-meri-cally pure tetra-dentate ligand N,N'-bis-(3,5-dichloro-2-hy-droxy-benz-yl)-trans-(R,R)-1,2-diamino-cyclo-hexane. The metal centre is eight-coordinate and displays a distorted dodeca-hedral coordination environment with average Zr-O and Zr-N bond lengths of 2.082 (9) and 2.441 (8) Å, respectively. In the crystal structure, complex mol-ecules are linked by inter-molecular C-H⋯Cl hydrogen-bond inter-actions into zigzag chains running parallel to the [101] direction. C-H⋯O and N-H⋯O hydrogen bonds are also present.

In the title complex, [Fe(C(22)H(24)N(2)O(4))]·H(2)O, the Fe(II) center is four-coordinated by two O and two N atoms from 2,2'-[6,6'-dimethoxy-cyclo-hexane-1,2-diylbis(nitrilo-methyl-idyne)]diphen-olate (L) ligands in a distorted square-planar geometry. Uncoordinated water and FeL mol-ecules are paired via inter-molecular water-meth-oxy O-H⋯O hydrogen bonds.
