| Popis: | New organic–inorganic hybrid compound, with formula (C4H6N3O)6[(HAsO4)2Mo6O19]⋅7H2O, was prepared and characterized by IR and UV–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 − 1, Z = 2) was determined by X-ray diffraction. The compound contains the polyanion [(HAsO4)2Mo6O19]6−, 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 ⋯ O and O–H ⋯ O hydrogen bonds. Furthermore, the electrochemical property of this compound has been studied. |
