Carboxylate-ligand substitution reactions of paddlewheel-type diruthenium(ii, iii) complexes ([Ru2II,III(RCO2)4]+) with 2,6-bis(trifluoromethyl)benzoate (2,6-(CF3)2PhCO2-) involving a selective reduction to [Ru2II,II] provide a series of trans-substituted paddlewheel-type diruthenium(ii, ii) complexes, [Ru2II,II(2,6-(CF3)2PhCO2)2(RCO2)2(THF)2] (R = CH3, 1; C2H5, 2; C3H7, 3; C4H9, 4; C(CH3)3, 5; 2,3,5,6-F4Ph, 6). Crystal structures of 1-6 were determined, and their electronic states were investigated by cyclic voltammetry, density functional theory (DFT) and magnetic measurements. This is the first example of trans-heteroleptic carboxylate-bridged [Ru2II,II] complexes.
