catena-Poly[copper(II)-bis(μ-2,4-dichloro-6-formylphenolato)-κ3O,O′:Cl4;κ3Cl4:O,O′]
Abstract
In the title compound, [Cu(C7H3Cl2O2)2]n, the CuII atom lies on a centre of inversion and adopts a [4+2] coordination mode, with two long axial Cu—Cl coordinative bonds complementing four Cu—O bonds from two 2,4-dichloro-6-formylphenolate ligands in a distorted square plane. π–π stacking interactions are also formed between neighbouring aromatic rings, with a centroid–centroid separation of 3.624 (2) Å.
