byproducts: NH3; oxidation of CsNH2 with formation of CsNO2 beside CsOH and NH3;;

in neat (no solvent) byproducts: N2O, N2; NO was passed over CsOH forming CsNO2 beside N2O and little amount of N2;;

in water double decompn. of aq. solns. at 298K followed by slow evapn.;; after recrystn. from aq. soln.; the prod. was washed with a small amt. of EtOH, dried in vac. at 120°C; purification by zone-melting (20 passes); the Cs salt was contaminated by Rb (0.01percent), Na (0.92percent), K (0.002percent) and NO3(1-) (<0.1percent); elem. anal.;;

in not given metathesis of CsCl with AgNO2 with formation of CsNO2;;

in ammonia a soln. of Cs in liquid NH3 was shaked for a longer period of time with O2 forming Cs2O4;; formed Cs2O4 is impured with traces of CsNO2 and CsNO3;;

in ammonia a suspension of Cs2O2 in liquid NH3 was treated with O2 forming Cs2O3;; formed Cs2O3 is contamined with unreacted Cs2O2, with Cs2O4 and traces of CsNO2 and CsNO3;;

byproducts: H2O; at room temp.;
