【Abstract】 (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 a=11.3577（9）,b=12.2030（10）,c=18.1588（14）,α=80.866（2）°,β=78.170（2）°,γ=88.783（2）°,V=2431.9（3）³,Z=2,and 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.更多还原
