Caesium Chromate, Cs2CrO4, obtained by interaction of silver chromate and caesium chloride in boiling aqueous solution, is yellow in colour, and exists in two crystalline forms - rhombic (bipyramidal):
a:b:c = 0.5640:1:0.7577;
and rhombohedral:
a:c = 1:1.2314; α = 72° 39'.
It forms a double salt, Cs2Mg(CrO4)2.6H2O, isomorphous with the corresponding rubidium salt. |
