【 摘 要 】

New organicâ€�?�inorganic hybrid compound, with formula (C₄H₆N₃O)₆ [(HAsO₄)₂Mo₆O₁₉].7H₂O, was prepared and characterized by IR and UVâ€�?�visible spectroscopies and X-ray diffraction techniques. Thermal analysis was performed to study their thermal stability. The crystal structure of the title compound (triclinic, space group $P âˆ�? 1$, ð‘�? = 2) was determined by X-ray diffraction. The compound contains the polyanion [(HAsO₄)₂Mo₆O₁₉]^6âˆ�?, which consists of the six molybdenum octahedral grouped into two parts consisting of four edge-sharing octahedral and two face-sharing octahedral, respectively, these two parts are connected by two corner-sharing O atoms to form a bent Mo₆ ring. The polyanion framework derives from the Strandberg type and it is a new isomer. The cytosinium cations (Cyt⁺) are embedded in the channels and interact with the inorganic framework by way of N-H $cdots$ O and O-H $cdots$ O hydrogen bonds. Furthermore, the electrochemical property of this compound has been studied.
