【摘要】 应用水热合成法且以乙二铵为膜板剂合成了一种结构新颖的磷酸镓化合物[H3N(CH2)2NH3]1/2.[Ga5(PO4)4(OH)4]。利用单晶X射线衍射仪对其结构进行分析,有关晶体数据如下:空间构型,单斜C2/m,a=1.0160(9)nm,b=1.2008(15)nm,c=0.7189(7)nm,β=90.797(6)°,V=0.87708(16)nm3,Z=2,R1=0.0264,wR2=0.0764。其结构是由一个新颖的次级结构单元(SBU)Ga4P4O20(OH)4构建而成,在SBU中Ga处于变形的三角双锥构型,P处于四面体构型。SBU通过桥氧连接成层,层与层间通过GaO4(OH)2八面体连接成三维框架结构。更多还原

【Abstract】 A new three-dimensional open-framework gallophosphate:[H₃N（CH₂）₂NH₃]_1/2·[Ga₅（PO₄）₄（OH）₄] was prepared by hydrothermal method in the presence of ethylenediamine（en） as a structure-directing agent.Its structure was determined by means of single-crystal X-ray diffraction analysis with the following crystal data:monoclinic space group C2/m,a=1.0160（9）nm,b=1.2008（15）nm,c=0.7189（7）,β=90.797（6）°,V=0.87708（16）nm³,Z=2,R₁=0.0264,wR₂=0.0764.It is built up by a new secondary building unit（SBU） Ga₄P₄O₂₀（OH）₄,in which Ga atoms exhibit distorted trigonal bipyramidal coordination and P atoms are in tetrahedral coordination.The SBU Ga₄p₄O₂₀（OH）₄ are linked into a layer by bridge oxygen atoms.The GaO₄（OH）₂ octahedra link the layers into a three-dimentional framework.更多还原
