their chemistry for the formation of ternary mixed‐metal chalcogenide nanoclusters, two sets of thermally stable, N‐heterocyclic carbene metal–chalcogenolate complexes of the general formula [(IPr)Ag−ESiMe3] (IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene; E=S, 1; Se, 2) and [(iPr2‐bimy)Cu−ESiMe3]2 (iPr2‐bimy=1,3‐diisopropylbenzimidazolin‐2‐ylidene; E=S, 4; Se, 5) are reported. These are prepared
作为制备新的“金属仲硫氰酸盐”前体并发展其化学性质以形成三元混合金属硫属元素化物纳米团簇的努力的一部分,这两组热稳定的通式为[(IPr)Ag的N-杂环卡宾金属-硫属元素酸盐配合物-ESiMe 3 ](IPr = 1,3-双(2,6-二异丙基苯基)咪唑啉-2-亚基; E = S,1 ; Se,2)和[(i Pr 2 -bimy)Cu-ESiMe 3 ] 2(i Pr 2 -bimy = 1,3-二异丙基苯并咪唑啉-2-亚基; E = S,4 ; Se,5)的报告。它们分别由相应的卡宾金属乙酸盐,[(IPr)AgOAc]和[(i Prbibimy)CuOAc]与E(SiMe 3)2在低温下反应制得。的反应[(IPR)的Ag-ESiMe 3 ] 1与汞(II),乙酸,得到杂金属配合物[(IPR)AGS} 2汞柱] 3含有两个(IPR)AGS -片段结合到汞柱中央II,代表汞-硫化银的混合配合物。[[
