In the title layered coordination polymer, {[Cd(C17H18F2N3O3)(C8H4O4)]·3H2O}n, the CdII atom exhibits a very distorted CdO6 octahedral geometry defined by one O3,O4-bidentate 1-ethyl-6,8-difluoro-7-(3-methylpiperazin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (lome) ligand, one O,O′-bidentate benzene-1,4-dicarboxylate (bdc) dianion and two O-monodentate bdc dianions. Both the bdc species in the are completed by crystallographic inversion symmetry. The bridging bdc dianions link the cadmium nodes into a rectangular grid lying parallel to (01). A network of N—H⋯O and O—H⋯O hydrogen bonds helps to establish the packing.

A mixture of Cd(NO3)2.2H2O (0.5 mmol), lomefloxacin (0.6 mmol), 1,4-benzenedicarboxylic acid (0.25 mmol), and water (12 ml) was stirred for 30 min in air. The mixture was then transferred to a 25 ml Teflon reactor and kept at 433 K for 72 h under autogenous pressure. Colourless single crystals of (I) suitable for X-ray analysis were obtained from the reaction mixture.
The H on the C atoms and N atoms were positioned geometrically (C—H = 0.93–0.97 Å, N—H = 0.86 Å) and refined as riding with Uiso(H) = 1.2Ueq(C or N). The H atoms on water molecules were placed at chemically sensible positions on the basis of hydrogen bonds, but these were not refined, O—H = 0.85 Å and U(H) = 1.5Ueq(O).
Lomefloxacin (H-Lome,1,4-dihydro-6,8-difluoro-1-ethyl-7- (3-methyl-1-piperazinyl)-4-oxo-3-quinoline carboxylic acid) is a new member of the class of quinolones that is used to treat infections (Mizuki et al., 1996). The metal complexes of lomefloxacin have not been reported.
The title cadmium(II)-containing complex of lomefloxacin, (I), is reported here (Fig. 1).
The structure of (I) is built up from Cd2+ cations, lome ligands, 1,4-benzenedicarboxylate anions, three uncoordinated water molecules (Fig. 1). The Cd atom exhibits a distorted CdO6 octahedral geometry, two O atom come from one bidentate O,O-bonded 1,4-dihydro-6,8-difluoro-1-ethyl-7-(3-methyl-1-piperazinyl)-4-oxo-3-quinoline carboxylic (lome) and four O atom come from three 1,4-benzenedicarboxylic acid molecules.
In title compound (I) form a square grid propagating in (Fig. 2) which 1,4-benzenedicarboxylic acid is bridged ligands.
The components of (I) are linked by O—H···O and O—H···N hydrogen bonds involving all the potential donors, generating a three-dimensional supramolecular network.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Lomefloxacin (H-Lome,1,4-dihydro-6,8-difluoro-1-ethyl-7- (3-methyl-1-piperazinyl)-4-oxo-3-quinoline carboxylic acid) is a new member of the class of quinolones that is used to treat infections (Mizuki et al., 1996). The metal complexes of lomefloxacin have not been reported.
The title cadmium(II)-containing complex of lomefloxacin, (I), is reported here (Fig. 1).
The structure of (I) is built up from Cd2+ cations, lome ligands, 1,4-benzenedicarboxylate anions, three uncoordinated water molecules (Fig. 1). The Cd atom exhibits a distorted CdO6 octahedral geometry, two O atom come from one bidentate O,O-bonded 1,4-dihydro-6,8-difluoro-1-ethyl-7-(3-methyl-1-piperazinyl)-4-oxo-3-quinoline carboxylic (lome) and four O atom come from three 1,4-benzenedicarboxylic acid molecules.
In title compound (I) form a square grid propagating in (Fig. 2) which 1,4-benzenedicarboxylic acid is bridged ligands.
The components of (I) are linked by O—H···O and O—H···N hydrogen bonds involving all the potential donors, generating a three-dimensional supramolecular network.
