Abstract:

Hydrothermal reactions of substituted phthalic acid with lanthanide salts lead to two kinds of coordination polymers containing linear lanthanide-oxygen clusters, where the different coordination patterns are attributed to the effect of lanthanide contraction. Five coordination polymers containing linear lanthanide-oxygen clusters 1-5 have been synthesized by a hydrothermal reaction of 3-(quinolin-8-yloxy) phthalic acid ((HL)-L-2) with the respective lanthanide salt. The X-ray single crystal structural analyses revealed that these five crystalline materials belong to two isostructures with formulas [LnHL(2)(H2O)(2)](n) (Ln1, where Ln = La 1, Ce 2, Pr 3) and [Ln(HL)(L)(H2O)](n) (Ln2, where Ln = Nd 4, Sm 5), respectively, which are attributed to the effect of lanthanide contraction. In both structures, the lanthanide cations were bridged by two carboxyl groups of L2- through Ln-O bonds to form 1-D linear lanthanide-oxygen clusters, which were further connected by intermolecular pi-pi stacking interactions between quinolinyl units to generate 3-D supramolecular polymers with moderate luminescence and high thermal stability.
