Abstract:
The asymmetric unit of the title coordination polymer, [Cu(C(18)H(16)Br(2)N(2)O(2))](n), consists of a Schiff base complex in which 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 dimer units, which are twisted around Cu(II) atoms in a bis-bidentate coordination mode. In the crystal, these dimeric units are connected through Cu-O bonds, forming one-dimensional coordination polymers, which propagate along [001]. The Cu(II) atom adopts a square-based pyramidal coordination geometry, being coordinated by two N and two O atoms of symmetry-related ligands and by a third O atom of a neighboring complex. Furthermore, inter-molecular π-π inter-actions [centroid-centroid distance = 3.786 (2) Å] and C-H⋯O inter-actions stabilize the crystal packing.
