Abstract

Abstract : Zirconium-based metal organic frameworks (MOFs) are of great significance in supramolecular coordination chemistry, mainly as catalysts, due to their chemical stability and structural diversity. Abstract : Zirconium-based metal organic frameworks (MOFs) are of great significance in supramolecular coordination chemistry, mainly as catalysts, due to their chemical stability and structural diversity. We report the synthesis of zirconium-clathrochelate based crystalline MOFs (Zr-GU- 1 to - 4 ) made from hexanuclear zirconium inorganic nodes and iron(ii ) clathrochelate-based ditopic carboxylic acid ligands bearing various lateral moieties, namely, butyl, cyclohexyl, phenyl and methyl groups. Among the various iron(ii ) clathrochelate linkers, the one with butyl side chains, i.e., Zr-GU- 1, forms stable crystalline MOFs as confirmed by single-crystal X-ray crystallography and exhibits a promising porosity with a BET surface area of ∼650 m 2 g −1 after its activation with supercritical CO2 (ScCO2 ) from acetonitrile.
