{5,5'-Bis(methoxy-carbonyl-meth-oxy)-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]-diphenolato}copper(II).

ABSTRACT: The title compound, [Cu(C(22)H(22)N(2)O(8))], is a tetra-dentate Schiff base complex. The Cu(II) ion has a nearly square-planar geometry, being coordinated by two N atoms and two O atoms. The two chemically equivalent halves of the mol-ecule are crystallographically independent. One of the carboxylic acid methyl ester units is located in the main plane of the mol-ecule and the other is rotated by 65.3 (5)° with respect to this unit. In the crystal structure, there are π-π stacking inter-actions between adjacent six-membered chelate rings, with centroid-to-centroid distances of 3.602 (2) Å.
