Syntheses, Structures, and Luminescence Property of Two New Supramolecular Complexes Containing a Flexible Carboxylate

Two new complexes, namely [Cd(L)(2)(2,2'-bipy)] (1) and [(HL)(4,4'-bipy)(0.5)((H2O)] (2) (HL = 3-(2-hydroxyphenyl)propanoic acid, 2,2'-bipy = 2,2'-bipyridine and 4,4'-bipy = 4,4'-bipyridine), have been synthesized and structurally characterized by single-crystal diffraction analysis. The structure of complex 1 is molecular dimer, which is connected by stronger hydrogen bond interactions to result in a 2D network. While complex 2 is composed of two organic ligands molecular dimer and one water molecule, which also could be linked into a 2D supramolecular architecture via hydrogen bond interactions. Luminescence and its lifetime for compound 1 have also been explored.
