Synthesis, Photophysics, Electrochemistry, and Reactivity of Ruthenium(II) Polypyridine Complexes with Organoplatinum(II) Moieties. Crystal Structure of [Ru(bpy)₂(μ-2,3-dpp)PdCl₂]²⁺

A series of luminescent ruthenium(II) polypyridine complexes with organoplatinum(II) moieties, together with their chloro precursors and palladium(II) dichloro analogues, [Ru(bpy) 2 (BL)MX 2 ] 2+ (BL = 2,3-dpp, M = Pd, X = Cl ( 1 ); M = Pt, X = Cl ( 2 ), Cl and CH 3 ( 3 ), CH 3 ( 4 ), C 6 H 5 ( 5 ), C 6 H 4 -OCH 3 - p ( 6 ), C 6 H 4 -F- p ( 7 ); BL = bpm, M = Pd, X = Cl ( 8 ); M = Pt, X = Cl ( 9 ), Cl and CH 3 ( 10 ), C 6 H 5 ( 11 ), C 6 H 4 -CH 3 - o ( 12 ), C 6 H 4 -OCH 3 - p ( 13 ), C 6 H 4 -F- p ( 14 ); BL = 2,3-dpq, M = Pt, R = C 6 H 4 -OCH 3 - p ( 15 )) have been synthesized and their electrochemical and photophysical properties studied; their reactivities toward the oxidative addition of methyl iodide have been investigated. The X-ray crystal structure of 1 has been determined.
