Templated metal–organic frameworks: synthesis, structures, thermal properties and solid-state transformation of two novel calcium–adipate frameworks

Abstract

Two novel calcium–adipate framework materials have been synthesized hydrothermally. GWMOF-7 ([Ca(C₆H₈O₄)(H₂O)₂]·(C₁₀H₈N₂)) and GWMOF-8 ([Ca(C₆H₈O₄)(H₂O)₂]·(C₁₂H₁₂N₂)) both formed three-dimensional structures and were characterized with single-crystal X-ray diffraction, powder X-ray diffraction, IR spectroscopy and elemental analysis. Thermal properties were also studied with thermogravimetric analysis, and show that these structures undergo a solid-state transformation into a denser three-dimensional framework.
