摘　　要：以1,2-丙二胺为膜板剂应用水热法合成了一种具有新颖结构的亚磷酸镓化合物[Ga4(HPO3)6(H2O)2(OH)].C3H12N2.2H2O.晶体数据如下:空间构型,单斜P2(1)/n,a=1.13184(5)nm,b=1.10159(4)nm,c=1.87519(7)nm,β=92.569(3)°,V=2.33568(16)(nm)3,Z=4,R1=0.0353,wR2=0.0790.GaO6八面体和[HPO3]2-假四面体通过共顶点连接形成晶体的三维骨架.A new organically templated gallophosphite with formula [Ga4（HPO3）6（H2O2）（OH）]·C3H12N2·2H2O has been synthesized by using mild hydrothermal conditions under autogeneous pressure in the presence of 1,2-diaminopropan （dap） as structure--directing agent. Its structure is determined by means of single-crystal X-ray diffraction analysis with the following crystal data： Monoclinic space group P2（1）/n,a=1.13184（5）nm,b=1.10159（4）nm,c=1.87519（7）nm.β=92.569（3）°.V=2.33568（16）（nm）^3,Z=4,R1=0.0353,ωR2=0.0790. The three-dimensional framework is built up from GaO6 octahedral and [HPO3]^2- pseudopyramid by sharing vertices.
