Abstract

A new molecular porous zirconium-organic material, Zr{[NC 5 H 3 (CO 2 ) 2 ] 2 (OH 2 ) 2 }·1.3H 2 O (CAUMOF-12) has been synthesized by a hydrothermal reaction using Zr(NO 3 ) 4 , 2,6-NC 5 H 3 (CO 2 H) 2 , HNO 3 and water at 180 °C. Single-crystal X-ray diffraction was used to determine the crystal structure of the reported material. Although the material can be classified as a molecular compound, CAUMOF-12 exhibits a pseudo-three- dimensional open-framework structure with void spaces obtained by intermolecular hydrogen bonds. CAUMOF-12 reveals differential gas adsorption characteristics and high thermal stability. Reversible hydration, facile ligand exchange reactions, and exclusive dimerization of phenylacetylene for CAUMOF-12 are presented, as are electronic structure calculations.
