Abstract
The novel cyclometalated Rh(III) complex, Rh(phpy-K-2 N, C-2
`)2(phen-dione)PF6, where phpy-K-2 N, C-2 ` 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, H-1 NMR, and electronic
absorption spectroscopies, cyclic voltammetry, and X-ray
crystallography. The crystal structure of Rh(phpy-K-2 N C-2
`)2(phen-dione)PF6 center dot CH3CN shows that the coordination
geometry around the Rh(111) is a distorted octahedron, with bite angles
of 76.13 degrees-81.09 degrees for all three bidentate ligands. (c) 2007
