A copper(II) complex of 1,10-phenanthroline and enrofloxacin

Abstract

The asymmetric unit of the title complex, aqua­[1-cyclo­propyl-7-(4-ethyl­piperazin-1-yl)-6-fluoro-4-oxo-1,4-dihydro­quinol­ine-3-carboxyl­ato](1,10-phenanthroline)copper(II) nitrate dihydrate, [Cu(C19H21FN3O3)(C12H8N2)(H2O)]NO3·2H2O, contains one [Cu(erx)(phen)(H2O)]+ cation, one NO3− anion and two solvent water mol­ecules (erx is enrofloxacin and phen is 1,10-phenanthroline). The CuII ion adopts a slightly distorted square-pyramidal geometry, coordinated by two O atoms of the erx ligand and two N atoms of the phen ligand in the basal plane, and by a water mol­ecule in the apical position. The CuII ion deviates from the basal plane by 0.1439 (7) A. The piperazine ring belonging to erx has a slightly twisted chair conformation. Coordinated and uncoordinated water mol­ecules participate in a hydrogen-bonding network including both cations and anions, to produce a three-dimensional supra­molecular structure.
