✦ Synopsis

Synthesis and Characterization of Some Heterometal-Substituted Ammonium Gallophosphates.

-The open framework structures of the four compounds (V) are isostructural to the known ammonium cobalt gallophosphate hydrate, (NH 4 ) [CoGa 2 P 3 O 12 (H 2 O) 2 ] (monoclinic, space group C2/c). The structure of this material is built up by trigonal GaO 5 bipyramids, distorted CoO 6 octahedra, and PO 4 tetrahedra. The gallophosphate molecular sieves (V) are thermally unstable and lose their microporous nature above 350 •
