Hydrothermal synthesis, crystal structure of two novel coordination polymers based on carboxylic acid ligand containing sulfur

Two new metal-organic polymers, [Zn(L-1)(2)(H2O)](n) 1 [H2L1 = 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid] and [La(HL2)(2)(L-2)(3)](n) 2 [HL2 = 2-thiophenecarboxylic acid], have been synthesized and characterized by elemental analysis, fluorescence spectra, and single-crystal X-ray diffraction. Polymer 1 and 2 are both coordination polymers that show one-dimensional and two-dimensional layers, respectively, in which they were constructed by interesting supermolecular architecture. In addition, complex 2 exhibits fluorescence at room temperature. This work will contribute the supermolecular construction with special steric architecture.
