Abstract
A convenient synthesis of the cyclometalated complex [{Rh(μ-Cl)(ptpy) 2 } 2 ] ( 2 , ptpy = 2-(p-tolyl)pyridinato) is described. Compound 2 was obtained by oxidative addition of Hptpy towards [{Rh(μ-Cl)(coe) 2 } 2 ] 1 (coe = cis -cyclooctene) in refluxing toluene in good yield. The complex 2 crystallized from chloroform/ iso -hexane in the space group P 2 1 / n as solvate 2*2 CHCl 3 and its molecular structure was confirmed by a single-crystal X-ray diffraction study. The emission spectrum exhibits the new compound as green-emitting phosphorescent complex. A convenient synthesis of [{Rh(μ-Cl(ptpy) 2 } 2 ] ( 2 , ptpy = 2-(p-tolyl)pyridinato) is described. The crystal and molecular structure of 2 was determined by X-ray crystallography. The emission spectrum of 2 exhibits the complex as green-emitting compound. ►Convenient synthesis of the new cyclometallated complex[{Rh(μ-Cl(ptpy) 2 } 2 ] ( 2 , ptpy = 2-(p-tolyl)pyridinato). ►X-ray crystallography shows that only the ΛΛ, ΔΔ racemate of 2 is formed. ►2 is a green emitter.
