The structures of ammonium manganese(II) dialuminium tris-(phosphate) dihydrate, (NH)MnAl(PO)·2HO, and ammonium nickel(II) dialuminium tris-(phosphate) dihydrate, (NH)NiAl(PO)·2HO, were determined using single-crystal diffraction data. The structures of title compounds are isotypic to cobalt aluminophosphate, (NH)CoAl(PO)·2HO (LMU-3) [Panz (1998 ▸). , , 73-82], in which a three-dimensional network of vertex-sharing AlO and PO moieties delineate twelve-membered channels in which ammonium, NH , and transition-metal cations ( = Mn and Ni) reside as charge compensators for the anionic [Al(PO)] aluminophosphate framework. In both structures, the N atom of the ammonium cation, the transition-metal ion and one of the P atoms lie on crystallographic twofold axes.
利用单晶衍射数据测定了二水合磷酸二铝锰（II）铵（(NH₄)₂MnAl₂(PO₄)₃·2H₂O）和二水合磷酸二铝镍（II）铵（(NH₄)₂NiAl₂(PO₄)₃·2H₂O）的结构。标题化合物的结构与钴铝磷酸盐（(NH₄)₂CoAl₂(PO₄)₃·2H₂O ，LMU - 3）[Panz (1998 ▸). , , 73 - 82] 同型，其中由顶点共享的AlO和PO部分构成的三维网络勾勒出十二元通道，铵根离子（NH₄⁺）和过渡金属阳离子（ = Mn和Ni）作为阴离子[Al(PO₄)]铝磷酸盐骨架的电荷补偿剂存在于其中。在这两种结构中，铵阳离子的N原子、过渡金属离子和一个P原子位于晶体学二重轴上。
