摘　　要：采用水热法制备1,2二-吡啶基乙烷-钼磷酸盐(C12H14N2)2.PMo12O40,并用元素分析,红外光谱和单晶X射线衍射对其进行表征.该晶体属于三斜晶系,P(-1)空间群,晶胞参数a=11.3577(9)A°,b=12.2030(10)A°,c=18.1588(14)A°,α=80.866(2)°,β=78.170(2)°,γ=88.783(2)°,V=2431.9(3)A°3,Z=2,R1=0.0454,wR2=0.0880.该晶体由十二钼磷酸阴离子和质子化的1,2二-吡啶基乙烷分子通过静电引力和氢键相互作用堆积而成.UV-VIS-NIR反射光谱表明,该晶体在4.0—1.5 eV都有较强的选择性吸收.（C12H14N2）2·PMo12O40 has been obtained via a hydrothermal reaction of H3 [ P（ Mo3O10 ）4 ] · xH2O, ZnO and 1,2-bis（4-pyridyl）ethane. EDS, IR spectra and X-ray crystal structure analysis were carried out to determine its composition and crystal structure. The crystal belongs tomonoclinic space group P （ - 1 ） with lattice parameters n=11.3577（9）A,b=12.2030（10）A,c=18.1588（14）A,a=80.866（2）°,β=78.170（2）°,γ=88.783（2）°,V=2431.9（3）A^3,Z=2,R1=0.0454,wR2=0.0880. （PMo12O40）^4- anions and protonated 1,2-bis（4-pyridyl） ethane pack to construct the crystal structure though electrostatic interactions and hydrogen bonds. Its optical absorptive characteristic is obtained by the measurement of diffuse reflectivity.
