Solvothermal synthesis and characterization of a lithium coordination polymer possessing a highly stable 3D network structure

Solvothermal reaction of lithium perchlorate and 1,4-benzene dicarboxylic acid at 180 °C has resulted in a novel lithium coordination polymer Li2 (CO2–C6H4–CO2), which is characterized by single crystal X-ray diffraction analysis, X-ray powder diffraction analysis, elemental analysis, TGA/DTA and IR spectra. The compound shows a remarkable high thermal stability up to 530 °C, features a new 3D network containing two types of 6-membered ring and 18-membered dumbbell-like ring in view from different directions.
