A convenient synthesis of the cyclometalated complex [{Rh(mu-Cl)(ptpy)(2)}(2)] (2, ptpy = 2-(p-tolyl)pyridinato) is described. Compound 2 was obtained by oxidative addition of Hptpy towards 1[{Rh(mu-Cl)(coe)(2)}(2)] 1 (coe-=cis-cyclooctene) in refluxing toluene in good yield. The complex 2 crystallized from chloroform/isohexane in the space group P2(1)/n as solvate 2*2 CHCl3 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.
