Abstract

The synthesis and crystal structure of the one-dimensional coordination polymer, [Cd(spar)₂]_n•n(H₂O), are described, where spar^- is the sparfloxacinate anion, C₁₉H₂₁N₄O₃F₂ ^-. The Cd²⁺ ion is bonded to four spar^- ligands: Two O,O-chelate with their β-keto carboxylate groupings and two are monodentate-bound through a carboxylate O atom, to result in a distorted CdO₆ octahedral coordination geometry. The bridging ligands lead to [100] polymeric chains in the crystal and N-H⋯O hydrogen bonds and possible weak aromatic p-p stacking interactions help to consolidate the structure. Crystal data: C₃₈H₄₄CdF₄N₈O₇, M_r = 913.21, triclinic, (No. 2), Z = 2, a = 9.2256(4) Å, b = 12.8767(5) Å, c = 17.4297(7) Å, α = 89.505(2)°, β = 85.062(2)°, g = 70.757(2)°, V = 1947.20(14) Å³, R(F) = 0.036, wR(F²) = 0.082.
