Cyclometalated rhodium(III) complex with phen-dione ligand

Abstract: The novel cyclometalated Rh(III) complex, , where 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 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. [Copyright &y& Elsevier]
