Self-assembly of quinolones with metal salts in the presence of aromatic dicarboxylate ligands affords a series of novel 1D metal-quinolone complexes, namely [Mn(Hppa)(oba)]center dot 3H(2)O (1), [Co(HPPa)(oba)]center dot 3.25H(2)O (2), [Zn(Hppa)(sdba)]center dot 1.5H(2)O (3), [Mn(Hcf)(bpda)(H2O)]center dot 2H(2)O (4), [Mn(Hppa)(2)(bpdc)] (5) and [Mn(Hlome)(2)(bpdc)]center dot 4H(2)O (6) (Hppa = Pipemidic acid, Hcf = ciprofloxacin, Hlome = lomefloxacin). The structures of compounds 1-3 consist of novel polymeric chains spanning two different directions, which display an intriguing 1D -> 3D inclined polycatenation of supramolecular ladders. Compound 4 exhibits a chain compound formed from the interconnection of [Mn-2(Hcf)(2)(mu-CO2)(2)] dimers with bpda ligands. Compounds 5 and 6 are similar chain compounds constructed from [Mn(HPPa)(2)] (or [Mn(Hlome)(2)]) fragments linked by bpdc ligands. The magnetic properties of 4 have been studied, which indicate the existence of antiferromagnetic interactions. Furthermore, the luminescent properties of compound 3 are discussed.
