Abstract A new three-dimensional microporous fluorogallophosphate, named Mu-2,was synthesized from a fluoride-containing aqueous medium in thepresence of 4-amino-2,2,6,6-tetramethylpiperidine as organictemplate. The new material was characterized by microprobe analysis,thermal analysis, X-ray diffraction and solid state NMR spectroscopy.Its structure was determined from X-ray powder as well as singlecrystal data. The structure of Mu-2[Ga32P32O120(OH)16F8(C9H20N2H)4(C9H20N2H2)2 · 12H2O,M r = 6687.0, cubic, space group I23 (no. 197), a = 16.3782(2) Å, V = 4393.38(1) Å3, Z = 1, R F = 7.7% R wp = 10.7%] consists of acubic arrangement of double-four-ring units (D4R) hosting F− anionswhich are interconnected to form a three dimensional but interruptedframework. This arrangement generates a three-dimensional pore systemof eight-membered ring channels. Besides the D4R units, two othertypes of cages are present in the structure occluding the protonatedamine and a (OH)8-(H2O)6-cluster respectively.
