Structure, electrochemistry and spectroscopy of a new diacylhydrazido-bridged diruthenium complex with a strongly near-infrared absorbing RuIIIRuII intermediate

Original language description

Reaction of Ru(bpy)2Cl22 H2O with 1,2-bis(trifluoroacetyl)hydrazine H2(adc-CF3) under basic conditions yields the dinuclear [(?-adc-CF3){Ru(bpy)2}2]2+ ion which was isolated and crystallized for structure determination in the meso diastereoisomer form asthe bis(hexafluorophosphate). The Ru Ru distance was determined at 5.029(1) ?, and the N?N bond length at 1.463(5) ? reveals a hydrazido(2) form of the bridge, implying unchanged + II metal oxidation states. Besides bpy-based reduction, the cyclic voltammetric analysis revealed two oxidation waves with a (3+) intermediate. Spectroelectrochemistry demonstrated that this intermediate [(?-adc-CF3){Ru(bpy)2}2]3+ with a comproportionation constant of Kc = 108.8 and an absorption at 1680 nm (? = 9900 M-1 cm1) is a mixed-valent species as evident most convincingly from the EPR parameters at g1 = 2.239, g2 = 2.065, g3 = 1.891 (gav = 2.101, ?g = g1 g3 = 0.348).
