The colorless Cs4ZrO4 is obtained from the reaction of stoichiometric proportions of Cs, CsO2, and finely divided ZrO2 in a sealed Ag container at 400–650°C for several days. Regrinding and re‐reaction provide a single phase sample. The compound is monoclinic (P21/c, Z = 4, a = 7.172 (1) Å, b = 19.907 (1) Å, c = 7.157 (1) Å, β = 113.1 (1)Å, R = 0.032) and isostructural with Cs4PbO4, with isolated ZrO4 4− tetrahedra (d(Zr–O) = 1.97 Å). The compound decomposes to Cs2ZrO3 (a) in the presence of excess oxygen or CsO2, (b) in high vacuum near 275°C, or (c) in a sealed container at about 730 ± 10°C.
