摘　　要：在水热体系中 ,制备了二维手性层结构的 ( 1 ,1 0 -phen) Ga2 ( HPO4 ) 2 F2 ( H2 O)无机 -有机杂化磷酸镓化合物 (简称 JGP-7) .用 X射线粉末衍射、元素分析、诱导耦合等离子体、红外光谱、热重分析和 X射线单晶衍射对其进行了表征 .单晶结构分析表明 ,该化合物属单斜晶系 ,P2 1 /c空间群 ,晶胞参数 a=0 .760 4( 1 ) nm,b=2 .1 691 ( 4) nm,c=0 .995 2 ( 2 ) nm,β=99.93 ( 3 )°,V=1 .61 93 ( 3 ) nm3,μ=3 .60 7mm- 1 ,Z=4,F( 0 0 0 ) =1 1 2 0 ,R1 =0 .0 3 75 ,w R2 =0 .0 5 69,GOF=0 .986.JGP-7的骨架由四元环组成的 Ga( 1 ) -P( 1 ,2 ) -O一维链与 Ga( 2 ) 2 F4 ( H2 O) 2 二聚体通过共用桥 O原子构成具有 4-,1 0 -元环的层状结构 ,无机层状结构间呈现手性对映 .这个无机层通过 1 ,1 0 -邻菲罗林配体相互作用形成的 π-π堆积扩展为三维超分子结构 .Phen)Ga 2(HPO 4) 2F 2(H 2O)(denoted JGP-7), a two-dimensional inorganic-organic hybrid gallophosphate with a chiral layered structure, was synthesized hydrothermally. It was characterized by X-ray powder diffraction(XRD), elemental analysis, inductively coupled plasma(ICP), IR spectra, TGA analysis and structurally determined by single-crystal X-ray diffraction analysis. JGP-7 crystallizes in the monoclinic system, space group P2 1/c(No.14), with a=0.760 4(1) nm, b=2.169 1(4) nm, c=0 995 2(2) nm, β=99.93(3)°, V=1.619 3(3) nm 3, μ=3.607 mm -1, Z=4, F(000)=1 120, R 1=0 037 5, wR 2=0.056 9, GOF=0.986. The layered structure of JGP-7 is constructed from Ga1-P(1,2)-O chains and Ga2 2F 4(H 2O) 2 dimers containing 4- and 10-rings along b-axis direction. It is noteworthy that JGP-7 exhibits chiral enantiomers of the structure between layers. The layers of JGP-7 are extended into a three-dimensional supramolecuar array via π-π stacking interactions of the 1,10-phen ligands.
