Lithium Based Metal-Organic Framework with Exceptional Stability

Abstract

A three-dimensional lithium based metal-organic framework Li-2(2,6-NDC) (1); UL-MOF-1, UL ultralight; NDC = napthalenedicarboxylate; space group P2(1)/c, a = 10.302(5), b = 5.345(2), c = 8.663(4) angstrom, beta = 98.659(9)degrees, V = 471.6(4) angstrom(3) was synthesized. The framework is stable to 610 degrees C. The synthesis of 1 was achieved using solvothermal methods in N,N-dimethylformamide at 180 degrees C and was characterized by single crystal X-ray diffraction. The structure consists of layers of two-dimensional antifluorite related LiO connected by the NDC linker.
