Lithium Based Metal−Organic Framework with Exceptional Stability

Abstract

A three-dimensional lithium based metal−organic framework Li₂(2,6-NDC) (<b>1</b>); UL-MOF-1, UL = ultralight; NDC = napthalenedicarboxylate; space group <i>P</i>2₁/<i>c</i>, <i>a</i> = 10.302(5), <i>b</i> = 5.345(2), <i>c</i> = 8.663(4) Å, β = 98.659(9)°, <i>V</i> = 471.6(4) ų was synthesized. The framework is stable to 610 °C. The synthesis of <b>1</b> was achieved using solvothermal methods in <i>N</i>,<i>N</i>-dimethylformamide at 180 °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.
