SYNTHESIS AND STRUCTURE OF TWO NEW FLUOROGALLOPHOSPHATES BUILT FROM A NOVEL CONNECTION SCHEME OF 2~13~4 PENTACYCLIC UNITS

摘要

The synthesis and structure of two new three-dimensional microporous fluorogallophosphates, Mu-16 and Mu-28, are reported. The materials are synthesized from N-methylpiperazine at 180℃ for 2 days, and from N, N'-dimethylpiperazine at 130℃ for 6 days, respectively. Their structures were solved using single crystal X-ray diffraction, and ~(31)P NMR spectroscopy. Mu-16 and Mu-28 exhibit a new arrangement of pentacyclic units. These fluorogallophosphates are characterized by XRD, SEM, elemental and thermal analyses, ~(13)C and ~(19)F NMR spectroscopy.
