Abstract

A new neutral triazole-based N-heterocyclic carbene rhodium(I) complex [RhCl(C₈H₁₂)(C₈H₁₅N₃)], has been synthesized and structurally characterized. The complex crystallizes with two molecules in the asymmetric unit. The rhodium center has a distorted square-planar conformation, formed by a cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chloride ligand.

A new neutral triazole-based N-heterocyclic carbene rhodium(I) complex [RhCl(C₈H₁₂)(C₈H₁₅N₃)], has been synthesized and structurally characterized. The complex crystallizes with two molecules in the asymmetric unit. The central rhodium(I) atom has a distorted square-planar coordination environment, formed by a cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chlorido ligand. The bond lengths are unexceptional. A weak intermolecular non-standard hydrogen-bonding interaction exists between the chlorido and NHC ligands.

氯[(1,2,5,6-η)-环辛烷-1,5-二烯](1-乙基-4-异丁基-1,2,4-三唑-5-亚基)铑(I)

一种新的中性三唑基 N-杂环碳化铑（I）络合物 [RhCl(C8H12)(C8H15N3)] 已被合成并具有结构特征。该复合物的不对称单元中含有两个分子。中心铑(I)原子有一个扭曲的方形平面配位环境，由一个环辛烷-1,5-二烯（COD）配体、一个 N-杂环碳（NHC）配体和一个氯配体形成。其键长并不特殊。氯配体和 NHC 配体之间存在微弱的分子间非标准氢键相互作用。
