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

Abstract

Two new metal–organic polymers, [Zn(L¹)₂(H₂O)]_n 1 [H₂L¹ = 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid] and [La(HL²)₂(L²)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.
