hydrogen bonding in CuI complexes. To this end, we have studied the coordination capacity of the tripodal phosphine ligands HTIM(PR2)3 tris[1‐(di‐R‐phosphanyl)‐3‐methyl‐1H‐indol‐2‐yl]methane, R = Ph, iPr} towards copper, leading to a series of eight CuI complexes [HTIM(PR2)3}CuX] [R = Ph (1–4), iPr (5–8); X = Cl–, I–, OTf–, BF4–]. An anagostic interaction in the CuI complexes has been proposed based
我们提出了Cu I络合物中非经典氢键的第一个例子。为此,我们研究了三脚架膦配体HTIM(PR 2)3 tris [1-(di-R-phosphanyl)-3-methyl-1 H-吲哚-2-yl]甲烷,R = Ph,i Pr}朝向铜,导致一系列八个Cu I络合物[HTIM(PR 2)3 } CuX] [R = Ph(1-4),i Pr(5-8); X = Cl –,I –,OTf –,BF 4 – ]。Cu I中的无声相互作用根据1 H NMR,超高分辨率X射线衍射以及电子密度的理论[分子内原子(AIM)和自然键合轨道(NBO)]分析,提出了配合物。在不同的合成配合物中,[HTIM(PPh 2)3 } CuOTf](2)显示出最强的Cu ··· H–C相互作用,具有线性几何形状(179.98°),并且是迄今为止描述的最短距离[ d(Cu -H)= 1.9Å],呈甲苯溶剂化形式。这两个
