Rhodium trifluoride is the inorganic compound with the formula RhF₃. It is a red-brown, diamagnetic solid.

Synthesis and structure[]

The compound is prepared by fluorination of rhodium trichloride:

2 RhCl₃ + 3 F₂ → 2 RhF₃ + 3 Cl₂

According to X-ray crystallography, the compound adopts the same structure as vanadium trifluoride, wherein the metal achieves octahedral coordination geometry.^[1]
