Gold(i) chloride complexes with the diarsenic ligands cis-1,4-dihydro-1,4-diarsinines (cis-DHDAs) were synthesized. X-ray diffraction revealed that they formed one-dimensional polymeric structures through aurophilic interactions. Their higher-ordered structures are controlled by the ligand structure; methyl- and t-butyl substituted ligands offered transoid-transoid and transoid-cisoid conformations, respectively. Density functional theory (DFT) calculations indicated that the electronic structure of the aurophilic network was highly dependent on the conformations. This is the first study on the relationship between the chain conformation and 5d-orbital structures of gold complexes.
合成了金(I)与二砷配体顺式-1,4-二氢-1,4-二砷杂环己二烯(cis-DHDAs)的氯化物配合物。X射线衍射表明,它们通过金亲作用形成一维聚合物结构。它们的高阶结构由配体结构控制;甲基和叔丁基取代的配体分别提供反式-反式和顺式-反式构象。密度泛函理论(DFT)计算表明,金亲网络的电子结构高度依赖于构象。这是首次关于金配合物链构象与5d轨道结构之间关系的研究。
