A new complex crystal (C10H9N2) 3.PMo12O40 (C10H9N2 is 2,2’-bipyridyl) was synthesized by hydrothermal method. Its chemical composition and structure were analyzed by IR, single crystal X-ray diffraction, X-ray spectrum and trace element analysis. The results show that the crystal structure of the complex belongs to the triclinic system with the space group P-1. The unit cell parameters a = 11.851 (2), b = 12.771 (3), c = 19.034 (4) (Kα) = 2.871 mm -1, β = 90.5 (3) °, γ = 112.6 (3) °, V = 2660.0 (9) 3, Z = 2, Dc = 2.864 mg / ) = 2176, R1 = 0.0416, ωR2 = 0.1327. The thermostability and conductivity of the crystal were analyzed by TG and UV-Vis-NIR diffuse reflectance spectroscopy. The crystal can exist stably under 250 ℃ with an optical energy gap of 0.8 eV and belongs to the semiconductor material.
