Abstract
The dinuclear complex [(tpy)RuII(PCP?PCP)RuII(tpy)]Cl2 (bridging PCP-PCP ) 3,3',5,5'-tetrakis(diphenylphosphinomethyl) biphenyl, [C6H2(CH2PPh2)2-3,5]2 2-) was prepared via a transcyclometalation reaction of the bis-pincer ligand [PC(H)P-PC(H)P] and the Ru(II) precursor [Ru(NCN)(tpy)]Cl (NCN ) [C6H3(CH2NMe2)2-2,6]-) followed by a reaction with 2,2':6',2''-terpyridine (tpy). Electrochemical and spectroscopic properties of [(tpy)RuII(PCP?PCP)RuII- (tpy)]Cl2 are compared with those of the
