Synthesis and structure of a square-planar copper-norflaxacin coordination complex.

ABSTRACT: The title coordination complex, bis-[4-(3-carboxyl-ato-1-ethyl-6-fluoro-4-oxo-1,4-di-hydro-quinolin-7-yl)piperazin-1-ium-κ² O ³,O ⁴]copper(II) dinitrate, [Cu(C₁₆H₁₈FN₃O₃)₂](NO₃)₂, was synthesized from norfloxacin (NF) and Cu(NO₃)₂·3H₂O. The asymmetric unit contains half a mol-ecule of [Cu(NF)₂] and one nitrate anion, with the copper atom located at a special crystallographic position with 1 site symmetry. The NF ligands are zwitterionic and coordinate to the metal atom via two oxygen atoms and the nitrate ions remain uncoordinated as counter-ions. The supra-molecular features include π-π stacking inter-actions as well
