of 1 M2 O3 (M = Ga or Al), 1 P2O5, 2 NH4F, 1 hexamethylenetetramine, and 80 H2O by hydrothermal synthesis at 180°C. Their crystal structure was determined by single-crystal X-ray diffraction. They crystallize in space group P212121, Z = 8, with cell parameters a = 9.593(2) Å, b = 9.742(2) Å, c = 9.981(2) Å and a = 9.416(8) Å, b = 9.563(5) Å, c = 9.933(4) Å, for M = Ga and Al, respectively. It appears
从1:1的混合物中,制得标题化合物中号2 ö 3(中号=镓或Al),1个P 2 ø 5,2 NH 4 F,1-六亚甲基四,和80h的2在180℃C 0通过水热合成。它们的晶体结构通过单晶X射线衍射确定。它们在空间组P 2 1 2 1 2 1中结晶,Z = 8,单元参数为a = 9.593(2)Å,b = 9.742(2)Å,c = 9.981(2)Å和a = 9.416(8) Å,b对于M = Ga和Al,分别为9.563(5)Å,c = 9.933(4)Å 。看来以前已经制备了铝磷酸盐并称为AlPO 4 -CJ2,但是表征较差。这些化合物的晶体结构可以被描述为PO的三维网络4四面体共享顶点与双三角锥MX 5和八面体MX 6(X = O 2 - ,OH -或F - )。这些多面体形成八元环并划定通道,其中铵基团占据两种类型的位点。取决于M,氟原子占据一个或两个不同的位置,或者完全占据或统计
