Properties
Rubidium peroxide is a colourless to light yellow solid with the
orthorhombic crystal structure
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 a r ...
