水热法合成了一系列金属硼磷酸盐Na_2 [MIIB_3P_2O_（11）（OH）]·0.67H_2O（MII=Mg，Mn，Fe，Co，Ni，Cu，Zn），并用单晶衍射技术确定了它们的结构。它们都属于P63六方晶系，形成了由八面体（MIIO 6）、四面体（BO 4，PO 4）和三角形（BO 2（OH））单元组成的12元环通道的三维微孔结构，Na+离子和水分子位于其中。Na+阳离子是移动的，并且可以在LiNO3的熔体中被Li+交换。它们的开放框架在高达约500°C下是热稳定的。也可以获得两种不同过渡金属之间的完全固溶体。研究了Na_2 [MIIB_3P_2O_（11）（OH）]·0.67H_2O（MII=Mn，Co，Ni，Cu）的磁性。
A series of metalloborophosphates Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mg, Mn, Fe, Co, Ni, Cu, Zn) have been prepared hydrothermally and their structures have been solved by single-crystal diffraction techniques. They all crystallize in a hexagonal space group P63and form a 3D microporous structure with 12-membered ring channels consisted of octahedral (MIIO6), tetrahedral (BO4, PO4) and triangular (BO2(OH)) units, in which the counter Na+cations and water molecules are located. The Na+cations are mobile and can be exchanged by Li+in a melt of LiNO3. Their open frameworks are thermal stable up to about 500°C. Completed solid solutions between two different transition metals can also be obtained. Magnetic properties of Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mn, Co, Ni, Cu) have been investigated.
