Abstract:	Cr(ppy)3, a structural analog of the green phosphorescent Ir(ppy)3, emits even in solution at room temperature from a weakly distorted spin–flip state at 910 nm (Hppy = 2-phenylpyridine). The low energy arises from an enhanced covalence of the Cr–C bonds as compared to Cr–N bonds. Lower temperature reduces thermally activated decay increasing the emission intensity.
