Cyclometalated rhodium(III) complex with phen-dione ligand

The novel cyclometalated Rh(III) complex, [Rh(phpy-κ2N,C2′)2(phen-dione)]PF6[Rh(phpy-κ2N,C2′)2(phen-dione)]PF6, where phpy-κ2N,C2′phpy-κ2N,C2′ is pyridine-2-yl-2-phenyl and phen-dione is 1,10-phenanthroline-5,6-dione has been prepared and characterized by elemental analysis, IR, 1H NMR, and electronic absorption spectroscopies, cyclic voltammetry, and X-ray crystallography. The crystal structure of [Rh(phpy-κ2N,C2′)2(phen-dione)]PF6·CH3CN[Rh(phpy-κ2N,C2′)2(phen-dione)]PF6·CH3CN shows that the coordination geometry around the Rh(III) is a distorted octahedron, with bite angles of 76.13°–81.09° for all three bidentate ligands.
