摘要
采用水热法制备了一种新型磷酸铅三镁PbMg3(HPO4)(PO4)2，并用单晶x射线衍射对其进行了表征。该磷酸盐在单斜晶系中结晶，空间群为I2/m，晶胞参数为a = 6.6403(2)Å， b = 13.1169(5) Å， c = 10.7153(4) Å， β = 90.194(1)°。该结构由两个边共享的[MgO6]八面体连接到[PO4]或[HPO4]四面体组成[Mg2P2O14]和[Mg2H2P2O14]部分，它们通过顶点连接在一起，形成平行于（1 0 0）平面的薄片。此外，由[MgO6]八面体和[PO4]四面体共享一个顶点而形成的无限链（[MgPO9]∞）保证了薄片之间的连接，形成一个包含平行于b轴和c轴的隧道的三维结构。Pb2+和H+阳离子位于这些隧道中的无序位置。这种磷酸盐的结构也表现出很强的氢键。图形摘要(A)和(C)多面体结构表示，显示沿[010]和[001]方向的隧道，其中容纳了Pb和H原子。(C)隧道中的虚线表示氢键O1-H1…O1i。(B)由[MgO6]八面体和[PO4]四面体交替形成的无限链[MgPO9]∞，连接沿c轴堆叠的层。
Hydrothermal Synthesis and Structural Characterization of a New Lead Tri-magnesium Phosphate PbMg3(HPO4)(PO4)2
A new lead tri-magnesium phosphate PbMg3(HPO4)(PO4)2 was synthesized by hydrothermal method and characterized by single crystal X-ray diffraction. This phosphate crystallizes in the monoclinic system with space group I2/m and unit cell parameters a = 6.6403(2)Å, b = 13.1169(5) Å, c = 10.7153(4) Å and β = 90.194 (1)°. The structure consists of two edge-sharing [MgO6] octahedra linked to [PO4] or [HPO4] tetrahedra to build [Mg2P2O14] and [Mg2H2P2O14] moieties, which are interconnected together through vertices to form a sheet parallel to (1 0 0) plan. In addition, an infinite chain ([MgPO9]∞) formed by the sharing of a vertex between the [MgO6] octahedron and the [PO4] tetrahedron ensures the connection of the sheets to form a three-dimensional structure containing tunnels parallel to the b and c axes. The Pb2+ and H+ cations are located in disordered sites in these tunnels. The structure of this phosphate exhibits also a strong hydrogen bond.
