Abstract
The asymmetric unit of the title coordination polymer, [Cu(C18H16Cl2N2O2)]n, consists of a Schiff base complex in which the CuII atom adopts a square-pyramidal coordination geometry, being coordinated by two N and two O atoms of symmetry-related ligands and by a third O atom from a complex related by an inversion center. In the structure, a crystallographic twofold rotation axis bis­ects the central C—C bonds of the n-butyl spacers of the designated Schiff base ligands, making symmetry-related dimeric units, which are twisted around CuII atoms in a bis-bidentate coordination mode. In the crystal, these dimeric units are connected through the third bridging Cu—O bonds [2.3951 (13) Å], forming one-dimensional coordination polymers, which propagate along [001]. Furthermore, inter­molecular π–π inter­actions [centroid–centroid distance = 3.811 (1) Å] stabilize the crystal packing.
