Charge-transfer Layered Assembly of a trans-Heteroleptic Paddlewheel-type Diruthenium(II, II) Complex with a TCNQ Derivative: Electrochemical Tuning of the Magnetism
The first example of a charge-transfer assembly based on a trans-heteroleptic paddlewheel-type diruthenium (II, II) complex with a TCNQ derivative is reported: [trans-{Ru-2(CF3CO2)(2)-(2,6(CF3)(2)PhCO2)(2)}(2)TCNQ(OMe)(2)]center dot 2CH(2)Cl(2)center dot 2(p-xylene) (1; CF3CO2- = trifluoroacetate; 2,6-(CF3)(2)PhCO2- = 2,6-di(trifluoromethyl)benzoate; TCNQ(OMe)(2) = 2,5-bis(methoxy)-7,7,8,8-tetracyanoquinodimethane) and its CH2Cl2-free compound (1'), where the TCNQ(OMe)(2) moiety is neutral. Electrochemical magnetic tuning in 1' has been conducted using a Li-ion battery system, which induces a ferrimagnetic phase via the discharging process; in contrast, the pristine 1' complex is paramagnetic.
