Abstract

A novel dinuclear ruthenium(III) ONO pincer complex was synthesized from RuCl₃·H₂O and 2,6-pyridinedicarboxylic acid (H₂pydc) 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 P121/c1, 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-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.

含有 M-M 键的新型双核钌 (III) Ono 钳配合物的合成：X 射线衍射研究

摘要

_{以RuCl 3} ·H ₂ O和2,6-吡啶二甲酸(H ₂ pydc)为原料，以三乙胺为碱，在甲醇中合成了一种新型双核钌(III) ONO钳配合物。单晶 XRD 揭示了配合物的晶体性质，该配合物为单斜晶系，空间群P 121/ c 1，晶胞尺寸a  = 9.4603(7) Å，b  = 16.4025(12) Å，c  = 6.6844( 5) Å, β = 91.839(2)°。该配合物显示出罕见的反式构型'Ru(μ-OMe) ₂ (μ-O ₂ CN) ₂ Ru'核心以及单齿水配体配位。据我们所知，这是桥联双核钌配合物的罕见案例（只有几篇报道），也是第一个含有钳配体的案例。
