Synthesis of a Novel Dinuclear Ruthenium(III) Ono Pincer Complex Containing a M–M Bond: an XRD Study

A novel dinuclear ruthenium(III) ONO pincer complex was synthesized from RuCl 3 ·H 2 O and 2,6-pyridinedicarboxylic acid (H 2 pydc) in methanol by using triethylamine as a base. The single crystal XRD disclosed the crystalline nature of the complex that was found to be monoclinic, space group P 121/...

Description
Summary:A novel dinuclear ruthenium(III) ONO pincer complex was synthesized from RuCl 3 ·H 2 O and 2,6-pyridinedicarboxylic acid (H 2 pydc) in methanol by using triethylamine as a base. The single crystal XRD disclosed the crystalline nature of the complex that was found to be monoclinic, space group P 121/ c 1, with unit cell dimensions a  = 9.4603(7) Å, b  = 16.4025(12) Å, c  = 6.6844(5) Å, β = 91.839(2)°. The complex showed a rare transoid configuration ′Ru(μ-OMe) 2 (μ-O 2 CN) 2 Ru′ 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.
