AbstractTwo rare earth coordination polymers named {[La-6 (C9H11N2O4)(11)(H2O)(2)(OH)(2)] center dot Br-5}(n) (1) and [Gd(C9H11N2O4)(C2O4)(H2O)]n (2) (C9H11N2O42- = 1,3-bis(1-carboxylatoethyl) imidazolium ion, C2O42- = oxalate) were solvothermally synthesized using zwitterionic 1,3-bis(1-carboxylatoethyl) imidazolium bromide as ligand. 1 and 2 were both structurally characterized by single crystal X-ray diffraction, and their thermodynamic properties and magnetic properties of 2 were studied. In the 3D structure of 1 , La3+ ions are all ten-coordinated and exhibit three different coordination environments. This 3D structure of 1 is formed by La -O coordination bonds with Br- located in the cavities through H-bond and electrostatic attraction. Different from 1 , all Gd3+ ions in 2 have the same eight-coordinated environment. These two coordination polymers both have good thermostability until 323 degrees C for 1 and 375 degrees C for 2 , and then decompose giving rise to La2O3 and Gd2O3, respectively. The magnetic behaviors of 2 are measured in the temperature range 2-300 K. (C) 2021 Published by Elsevier B.V.
