ABSTRACT: The asymmetric unit of the title coordination polymer, [Cu(C(18)H(16)Cl(2)N(2)O(2))](n), consists of a Schiff base complex in which the Cu(II) 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 bis-ects 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 Cu(II) 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, in
