| Abstract: | A 1,4-benzene-bridged covalent hybrid of triarylamine and cyclometalated ruthenium 1(2+) was isolated as a bench-stable open-shell substance. The free spin in this complex is mainly associated with the triarylamine unit, as indicated by EPR and DFT calculations and electrochemical analysis. It exhibits an intense intervalence-charge-transfer transition around 1050 nm that is not present in 1(+) and 1(3+). |
