Abstract

The synthesis, structure and properties of the new microporous zinc phosphonate [Zn-2(H2PPB)(H2O)2]center dot xH(2)O (denoted as CAU-25, CAU stands for Christian-Albrechts-University) are presented. The crystal structure was determined by combining single crystal and powder X-ray diffraction data. The final refinement was carried out by using the Rietveld method. The structure contains one-dimensional channels between dense, corrugated, hydrogen bonded layers with a diameter of approximately 5 angstrom. While N-2 uptake was not observed at 77 K, CO2 and H2O uptakes were measured at 298 K.
