摘　　要：以无水乙醇和冰乙酸为溶剂,Co(NO3)2·6H2O,(1,3-二(4-吡啶基)丙烷(bpp)和(NH4)6[Mo7O24]·4H2O为反应物,在150℃下进行溶剂热反应,合成了新的无机-有机杂化材料Mo8O26(H2bpp)2。采用单晶X-射线衍射法测定晶体结构,通过紫外-可见-近红外反射光谱表征了晶体性能。研究表明,合成产物属单斜晶系,空间群P21/c,晶胞参数a=10.938(2),b=9.7351(19),c=19.649(4),β=101.74(3)°,V=2048.5(7)3;晶体结构由无机的[Mo8O26]n4-链和有机的(H2bpp)2+离子靠静电力和氢键堆积而成;此无机-有机杂化材料对紫外光具有较强的吸收,且有一定的质子导电能力。A novel inorganic-organic hybrid compound, Mo8026（Hzbpp）2 was synthesized by a solvothermal reaction of Co（N03）2· 6H20, （NH4）6[Mo7024]· 4H2O and 1, 3-bis（4-pyridyl）propane （bpp） in ethanol-acetic acid solution at 150 ℃ for 3 d ays. The crystal structure was determined by single-crystal X-ray diffraction, and o belongs in the monoclinic crystal system, space group P21/c with unit cell dimensions a = 10.938（2）A, b =9.7351（19）.A c = 19.649（4）A β= 101.74（3）°3 and V = 2048.5（7）A^3. The crystal structure is constructed from inorganic t[Mo8026]^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.
