title = "High Stabilization of Low Valency in a Homoleptic ortho-Hydroxybenzoate-bridged Paddlewheel Diruthenium(II,II) Complex",
abstract = "A paddlewheel-type homoleptic diruthenium(II,II) complex ([Ru2II,II]), [Ru2(o-OHPhCO2)4(THF)2] (o-OH), bridged by ortho-hydroxybenzoate (o-OHPhCO21) and tetrahydrofuran (THF) coordinated at the axial position (Lax) was isolated. The use of meta- and para-substituted hydroxybenzoate (x-OHPhCO21; x = m and p) produced the corresponding [Ru2II,III] species neutralized by deprotonation of one of the x-OHPhCO21 ligands. In the o-OH complex, the formation of intramolecular hydrogen bonds between the o-OH group and carboxylate oxygen atom stabilized the [Ru2II,II] species significantly.",
