Poly[Bis[Mu-1-Cyclopropyl-6-Fluoro-4-Oxido-7-(1-Piperazinyl)-1,4-Dihydro Quinoline-3-Carboxylato]Nickel(Ii)]

In the title compound, [Ni(C17H17FN3O3)(2)](n), the Ni-II atom exists in a distorted trans-NiN2O4 octahedral geometry defined by two monodentate N-bonded and two bidentate O, O-bonded 1-cyclopropyl-6-fluoro-4-oxido-7-(1-piperazinyl)1,4- dihydroquinoline-3-carboxylate (ciprofloxacinium) monoanions. The extended two-dimensional structure is a square grid. The Ni atom lies on a center of inversion.
