CoGaPO-5: Synthesis and crystal structure of (C6N2H14)(2)[Co4Ga5P9O36], a microporous cobalt-gallium phosphate with a novel framework topology

A microporous cobalt-gallium phosphate, (C6H14N2)(2)[Co4Ga5P9O36], has been synthesized under solvothermal conditions and the structure determined at 293 K by single-crystal X-ray diffraction (monoclinic, I 2/a, a = 15.002(2), b = 17.688(2), c = 15.751(2) Angstrom, beta = 97.24(1)degrees, V = 4146.3 Angstrom(3), Z = 4). The framework of this material is constructed from alternately linked MO(4) (M = Co or Ga) and PO4 tetrahedra, and it has a topology unlike that of any previously reported material. The DABCO template occupies sites within 2-dimensional intersecting networks of pores, which are surrounded by 8- and 10-membered rings. The structure has been approved by the Structure Commission of the International Zeolite Association and given the code CGF. (C) Elsevier Science Inc. 1997.
