- The salt [Rh(III)(phpy)₂(dtoxa)]Cl with phpy = 2-(2-pyridyl)phenyl anion and dtoxa = dithiooxamide has been characterized by its crystal structure and its electronic spectra. Since Rh(III) is rather redox-inert, the lowest-energy excited state of the complex cation is of the IL (dtoxa) type. In the solid state as well as in solution the complex is luminescent and displays a dtoxa IL phosphorescence at λₘₐₓ = 607 nm with φϕ = 10⁻³ and τ = 3.7 ns in CH₂Cl₂.
