Rubidium chlorate crystallizes in the trigonal crystal system with the space group R 3 m (space group no. 160) and the lattice parameters a = 608.9 pm and c = 817.4 pm, there are three formula units in the unit cell .

Chemical properties

When heated, rubidium chlorate breaks down into rubidium chloride and oxygen :

${\displaystyle \mathrm {2\ RbClO_{3}\longrightarrow 2\ RbCl+3\ O_{2}\uparrow } }$
