Abstract
Novel dinuclear ruthenium(III) ONO pincer complex was synthesized from [Ru(p-cymene)Cl2]2 precursor and 2,6-pyridinedicarboxylic acid (H2pydc) in methanol by using triethylamine as base. The single crystal XRD disclosed the crystalline nature of the complex that was found to be monoclinic, space group P121/c1, with unit cell dimensions a = 9.4603(7) Å, b = 16.4025(12) Å, c = 6.6844(5) Å, α = 90°, β = 91.839(2)° and γ = 90°. The complex showed a rare transoid configuration ‘Ru(m-OMe)2(m-O2CN)2Ru’ core along with monodentate aqua ligand coordination. To the best of our knowledge, this is a rare case of bridged dinuclear ruthenium complex (only a couple of reports) and the first one containing a pincer ligand.
