Homo- and heterodinuclear complexes of D2h-symmetric bis(chelate) ligand 2,2'-bipyrimidine with electron-rich metal fragments Mo(CO)4, Re(CO)3Cl, Cu(PPh3)2+, and Ru(bpy)22+
(LnM)(m-bpym)(MLn) (bpym = 2,2'-bipyrimidine, MLn, (MLn)' = Mo(CO)4, Re(CO)3Cl, Cu(PPh3)2+, Ru(bpy)22+) were synthesized and studied by cyclic voltammetry, absorption spectroscopy, and ESR of singly reduced forms. The individual capabilities of the low-valent metal fragments to undergo oxidn. and to shift the redn. potential of the bpym p acceptor ligand on coordination combine to result in variable electrochem. potential differences. After consideration of different Franck-Condon factors, absorption intensities, addnl. low-lying unoccupied orbitals of the bridging acceptor ligand, and solvatochromic effects, the considerably varying metal-to-ligand charge transfer transitions in the visible were assigned. on SciFinder(R)
