A new reaction: vacuum synthesis and characterization of IONO2 and IONO

The new reactions for preparing IONO2 and IONO have been found. IONO2 and IONO can be easily prepared in vacuum by the heterogeneous reactions of gaseous ICl over the solid powders AgNO3(s) at the room temperature and AgNO2(s) at 0(±1) °C which were loosely filled into the quartz inlet tube (about 1.5 cm inside diameter and 5 cm long) and supported on the quartz wool, respectively, and then are characterized well by the PES experiment and the ROVGF calculations.
