Synthesis, photophysics and electrochemistry of a novel luminescent organometallic ruthenium( II )/platinum( II ) binuclear complex and its ruthenium( II )/dichloro-platinum( II ) and palladium( II ) counterparts. X-Ray crystal structure of [Ru(bpy) ₂ (µ-2,3-dpp)PtCl ₂ ] ²⁺ [2,3-dpp = 2,3-bis(2-pyridyl)pyrazine]

A novel luminescent organometallic ruthenium(II)/platinum(II) binuclear complex, [Ru(bpy)2(µ-2,3-dpp)PtMe2]2+1 and its ruthenium(II)/dichloro-platinum(II) and palladium(II) analogues, [Ru(bpy)2(µ-2,3-dpp)PtCl2]2+2 and [Ru(bpy)2(µ-2,3-dpp)PdCl2]2+3 exhibit red 3MLCT emission at room temperature; the X-ray crystal structure of complex 2[2,3-dpp = 2,3-bis(2-pyridyl)pyrazine] is reported.
