摘　　要：Two large-pore metal-doped aluminophosphates, Mn4Al5（PO4 ）12[N（ C2H4NH3）3]3 [ N（C2H4NH3）2·（C2H4NH2）]（NH4）2·14H=O（Mn4-NJU） and Co4Al5（PO4）12[N（C2H,NH3）3][N（C2H4NH3）2（C2H4NH2）]3· （ NH4 ）4· 13H2O （ Co4-NJU） , which have the same open framework structures, were hydrothermally synthesized. The structures of these compounds consist of TO4 tetrahedra, which are linked together by corner-sharing to form an open framework with unique intersecting twelve-membered ring channels in three dimensions. The compounds crystallize in cubic space group I（-4）3m with α= 1. 6795（2） nm and V=4. 7374（9） nm^3 for Mn4-NJU, and a=1. 67372（19） nm and V = 4. 6887 （9） nm^3 for Co4-NJU, respectively. Single crystal structure analyses show that the protruding O atoms of the frameworks of the compounds are linked to protonated 4-（ 2-aminoethyl ）diethylenetriamine （TREN, C6H18N4 ） ions in the windows by means of hydrogen-bonding under the hydrothermal condition. It is also found that the components inside the super cages of the compounds are changeable, and the metal ions M^2＋ （M = Mn, Co） and Al^3＋ disorderedly occupy the same crystallographic positions.Two large-pore metal-doped aluminophosphates, Mn4Al5（PO4 ）12[N（ C2H4NH3）3]3 [ N（C2H4NH3）2·（C2H4NH2）]（NH4）2·14H=O（Mn4-NJU） and Co4Al5（PO4）12[N（C2H,NH3）3][N（C2H4NH3）2（C2H4NH2）]3· （ NH4 ）4· 13H2O （ Co4-NJU） , which have the same open framework structures, were hydrothermally synthesized.
