Solvothermal synthesis and characterization of a new 3D potassium Metal-Organic Framework (MOF) structure.

Abstract

Novel 3-D potassium- containing material [K(dhbdca)0.5],named RSUST-1 was synthesised solvothermally using 2,-5-dihydroxy-benzene-1,4-dicarboxylic acid (dhbdca) as ligand in a 1:1 H2O/DMA solvent mixture. The new material synthesised has been structurally characterised by means of single crystal X-ray diffraction, powder X-ray diffraction, infra-red spectroscopy, elemental analysis and thermogravimetric analysis (TGA). The single crystal X-ray diffraction studies show that [K(dhbdca)0.5],crystallize in the monoclinic P2(1)/n, space groups. The thermogravimetric analysis shows that the compound is thermally stable over a wide range of temperatures. Keywords: solvothermal Synthesis, Metal- Organic Framework structures, 3D metal structures.
