Rhodium(III) oxide (or Rhodium sesquioxide) is the chemical compound with the formula Rh2O3.

Structure

Rh2O3 has been found in two forms. The hexagonal form has the corundum structure. It transforms into an orthorhombic structure when heated above 750 °C.[1]

Safety

Conditions/substances to avoid are: extreme heat, organic solvents, hydrochloric acid, hydrosulfuric acid and ammonia.
