Abstract A novel dinuclear gold(II) complex with two-fold rotational symmetry 2 of general formula [Au 2 Cl 2 (diNHC) 2 ](PF 6 ) 2 (diNHC=di(N-heterocyclic carbene)) has been obtained in quantitative yield via chlorine (in the form of PhICl 2 ) oxidative addition to the parent gold(I) complex 1 [Au 2 (diNHC) 2 ](PF 6 ) 2 . The novel compound has been characterized by 1 H and 13 C NMR and single crystal x-ray structure analysis. The oxidation of the two gold(I) centres to gold(II), with the formation of a covalent bond between them, imposes to the complex an axis of chirality, along the Au–Au bond, leading to a chiral propeller arrangement. Graphical Abstract Structural characterization of a novel dinuclear gold(II) complex with di(N-heterocyclic carbene) ligands, the formation of the gold(II)-gold(II) bond imposes to the complex coordination chirality.

通过氯氧化加成定量选择柔性双核金（I）二（N-杂环卡宾）配合物中的轴向手性构象

摘要 定量获得了一种新型双核金(II)配合物，具有通式[Au 2 Cl 2 (diNHC) 2 ](PF 6 ) 2 (diNHC=di(N-杂环卡宾)) 2通过氯（以 PhICl 2 的形式）氧化加成到母体金 (I) 络合物 1 [Au 2 (diNHC) 2 ](PF 6 ) 2 中得到。该新型化合物已通过 1 H 和 13 C NMR 以及单晶 X 射线结构分析进行表征。两个金（I）中心氧化为金（II），在它们之间形成共价键，沿金-金键向配合物施加手性轴，导致手性螺旋桨排列。具有二（N-杂环卡宾）配体的新型双核金（II）配合物的图形摘要结构表征，
