The reaction between the sodium salt of 2‐oxyphosphinine and diphenylchlorophosphine leads to 2‐diphenylphosphinite phosphinine as a new chelating ligand. Copper(I) complexes are easily and quantitatively obtained when this compound is reacted with Cu I X (X = Cl, Br, I). The optical properties of these complexes were investigated; all of them show phosphorescence in the solid state at room temperature and emit orange‐red light in the range 658 to 702 nm with average lifetimes from 19.98 to 25.01 μs. The emission wavelength is tuned by the nature of the halide ligand: Cl – , which leads to a larger ligand‐field splitting, gives the longest emission wavelength, whereas I – , which generates a smaller ligand‐field splitting, leads to the shortest emission wavelength.
