【Abstract】 A novel inorganic-organic hybrid compound, Mo8O26(H2bpp)2 was synthesized by a solvothermal reaction of Co(NO3)2·6H2O, (NH4)6[Mo7O24]·4H2O and 1,3-bis(4-pyridyl)propane (bpp) in ethanol-acetic acid solution at 150 ℃ for 3 days. The crystal structure was determined by single-crystal X-ray diffraction, and belongs in the monoclinic crystal system, space group P21/c with unit cell dimensions a=10.938(2), b=9.7351(19), c=19.649(4), β=101.74(3)° and V=2048.5(7)3. The crystal structure is constructed from inorganic {[Mo8O26]4-}n anionic chains and organic (H2bpp)2+ cations linked by hydrogen bonds. The compound shows strong UV absorption and has a marked electron conductivity.更多还原
