Claim 3:
4. A method of making the 4,4′-divinylazobenzene-bridged diruthenium complex bearing two Ru(CO)Cl(PiPr3)2 moieties of claim 1, the method comprising:
stirring HRu(CO)Cl(PiPr3)2 in CH2Cl2 to obtain a first reaction mixture;
adding to the first reaction mixture a solution of 4,4′-diethynylazobenzene in CH2Cl2 to obtain a second reaction mixture;
stirring the second reaction mixture for at least about 1 hour;
removing the CH2Cl2 under reduced pressure to obtain a precipitate;
washing, filtering, and drying the precipitate; and
obtaining the 4,4′-divinylazobenzene-bridged diruthenium complex bearing two Ru(CO)Cl(PiPr3)2 moieties.
