摘　　要：以 1,3 丙二胺为模板剂 ,在溶剂热条件下合成了两个一维磷酸盐微孔分子筛 :[GaP2 O7(OH) ] [NH3 (CH2 ) 3 NH3 ] ( 1)和[Ge0 5GaP1 5O6 5(OH) 1 5] [NH3 (CH2 ) 3 NH3 ] ( 2 ) .X射线单晶结构解析表明 ,两个晶体结构分别由镓氧四面体和磷氧四面体 ,或镓氧四面体、锗氧四面体和磷氧四面体组成 ,并沿层c轴方向形成链 .这些链之间由 1,3 丙二胺相连 .1的结晶学数据为Mr=3 3 1 82 ,P 1,a =0 83 0 3 ( 2 )nm ,b =0 8614 ( 3 )nm ,c =0 8880 ( 2 )nm ,α =111 70 ( 3 )° ,β =10 7 5 9( 2 )° ,γ =98 3 9( 2 )° ,V =0 5 3 82 ( 3 )nm3 ,Z =1,MoKα ,λ =0 0 710 73nm ,R(F) =5 5 6% ,wR(F2 ) =14 3 6% .2的结晶学数据为 :P2 ( 1) /c ,a =0 88968( 7)nm ,b =1 675 62 ( 13 )nm ,c=0 83 666( 7)nm ,β =115 890 ( 2 ) ,V =1 12 2 0 8( 16)nm3 ,Z =4,MoKα ,R(F) =4 66% ,wR(F2 ) =10 10 % .Solvothermal syntheses and X ray crystal structures of two phosphates [GaP 2O 7(OH)][NH 3(CH 2) 3NH 3] (1) and [Ge 0 5 GaP 1 5 O 6 5 (OH) 1 5 ][NH 3(CH 2) 3NH 3] (2) are presented. Both structures are built up from GaO 4 and PO 4 tertrahedra or GeO 4 , GaO 4 and PO 4 tertrahedra which form chain along the crystallographic c axis. These chains are interconnected by 1,3 propanediamine molcules. Crystal data for 1: M r=331 82, space group P 1, a = 0 8303(2) nm, b =0 8614(3) nm, c =0 8880(2) nm, α =111 70(3)°, β =107 59(2)°, γ =98 39(2)°, V =0 5382(3) nm 3, Z =1, Mo K α , λ =0 071073 nm, R ( F )=5 56%, wR ( F 2)=14 36% for 202 parameters and 3136 reflections with I > σ ( I ) . Crystal data for 2: M r=358 13, space group P 2(1)/ c , a =0 88968(7) nm, b =1 67562(13) nm, c =0 83666(7) nm, β =115 890(2), V =1 12208(16) nm 3, Z =4, Mo K α , R ( F )=4 66%, wR ( F 2)=10 10% for 212 parameters and 1612 reflections with I >2 σ ( I ).
