Preparation and properties
Rubidium perchlorate can be obtained through the careful heating of a rubidium chlorate solution, leading to a
disproportionation
In chemistry, disproportionation, sometimes called dismutation, is a redox reaction in which one compound of intermediate oxidation state converts to two compounds, one of higher and one of lower oxidation states. More generally, the term can ...
reaction with the release of oxygen gas:
:2 RbClO
3 → RbClO
4 + RbCl + O

When heated, it decomposes into
the chloride and oxygen:
:RbClO
4 → RbCl + 2 O

It has two
polymorphs. Below 279 °C, it crystallizes in
orthorhombic crystal system
In crystallography, the orthorhombic crystal system is one of the 7 crystal systems. Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular prism with ...

lattice constant
A lattice constant or lattice parameter is one of the physical dimensions and angles that determine the geometry of the unit cells in a crystal lattice, and is proportional to the distance between atoms in the crystal. A simple cubic crystal has o ...
s ''a'' = 0.927 nm, ''b'' = 0.581 nm, ''c'' = 0.753 nm. Over 279 °C, it has a
cubic structure with lattice constant ''a'' = 0.770 nm.
