摘要：The title compound, [(Mo2O6)(pz)](pz = pyrazine), was hydrothermally synthesized by the reaction of pyrazine-2,3-dicarboxylic acid, CoCl2 · 6H2O, MoO3 and deionized water at 413K. This coordination compound crystallized in orthorhombic, space group Pbca with a=0.757 78(15) nm, b= 0.740 57(15) nm, c=1.411 2(3) nm, and Z=4. As characterized by single crystal X-ray diffraction, the 2-D inorganic molybdenum oxide layers were interlinked by bidenate organic pyrazine ligand into 3-D inorganic-organic hybrid material, in which each MoⅥ is coordinated by five oxygen atoms and one nitrogen atom in a distorted octahedral geometry. The result given by thermogravimetric analysis revealed that the title compound was thermally stable up to 300 ℃.%用吡嗪-2,3-二羧酸、CoCl2·6H2O、MoO3和去離子水在413K下通過水熱反應法得到了標題化合物[(Mo2O6)(pz)],該化合物晶體屬于正交晶系,空間群為Pbca,晶胞參數為a=0.757 78(15) nm, b= 0.740 57(15) nm, c=1.411 2(3) nm, Z=4. 單晶衍射數據表明標題化合物由二齒橋聯配體吡嗪將二維網狀[Mo2O6]n連接成具有三維網絡結構的無機-有機雜化化合物,其中每個Mo原子以變型八面體構型和5個氧原子以及1個氮原子配位. 標題化合物在300 ℃之前熱性能穩定.
