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.
