Bis{4,4',6,6'-tetra-chloro-2,2'-[trans-(R,R)-cyclo-hexane-1,2-diylbis(imino-methyl-ene)]diphenolato-κO,N,N',O'}zirconium(IV).

ABSTRACT: 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.

Project description:The Zn atom in the title acetonitrile solvate, [Zn(C(34)H(42)N(4)O(2))(C(2)H(6)OS)]·CH(3)CN, exists in a distorted square-pyramidal geometry with the basal plane defined by the N(2)O(2) atoms of the tetra-dentate Schiff base and with the dimethyl sulfoxide O atom in the apical position. The tetra-dentate mode of coordination of the Schiff base ligand leads to a five-membered ZnN(2)C(2) chelate ring which adopts an envelope conformation with the Zn atom at the flap, and two six-membered ZnOC(4)N chelate rings, one of which is approximately planar (r.m.s. deviation = 0.054 Å) but the other has significant puckering (r.m.s. deviation = 0.203 Å).
