%X The synthesis and crystal structure of the one-dimensional coordination polymer, [Cd(spar) 2] n¡¤ n(H 2O), are described, where spar £¿ is the sparfloxacinate anion, C 19H 21N 4O 3F 2 £¿. The Cd 2+ ion is bonded to four spar £¿ ligands: Two O,O-chelate with their ¦Â-keto carboxylate groupings and two are monodentate-bound through a carboxylate O atom, to result in a distorted CdO 6 octahedral coordination geometry. The bridging ligands lead to [100] polymeric chains in the crystal and N¨CH¡¤¡¤¡¤O hydrogen bonds and possible weak aromatic p¨Cp stacking interactions help to consolidate the structure. Crystal data: C 38H 44CdF 4N 8O 7, M r = 913.21, triclinic,£¿(No. 2), Z = 2, a = 9.2256(4) £¿, b = 12.8767(5) £¿, c = 17.4297(7) £¿, ¦Á = 89.505(2)¡ã, ¦Â = 85.062(2)¡ã, g = 70.757(2)¡ã, V = 1947.20(14) £¿ 3, R( F) = 0.036, wR( F 2) = 0.082.
