Additionally, the nonbridged derivatives [bis(trimethylgermyl-η6-benzene)M] (M = Cr, 10d; V, 11•), [(trimethylgermyl-η6-benzene)(η6-benzene)Cr] (10m), and [bis(triphenylgermyl-η6-benzene)M] (M = Cr, 14; V, 15•) were prepared and characterized by 1H- and 13C-NMR (10m, 10d, 14, 17, 20), cyclic voltammetry (CV) (10d, 11•, 14, 15•, 18•, 21•, 24), and EPR spectroscopy (10d•+, 11•, 14•+, 15•, 18•, 21•, 24•+)
单-和digerma [ Ñ ] metallocyclophanes(Ñ = 1,2)[(η 6,η 6 ' -dimethyldiphenylgermane)M](M =的Cr,17 ; V,18 •),[(η 6,η 6 ' - tetraphenylgermane)M](M =的Cr,20 ; V,21 •)和[(1,1,2,2-四甲基-1,2-二- η 6,η 6 ' -phenyldigermane)的Cr](24通过锂化并随后与二氯二甲基锗烷或二氯二苯基锗烷反应来合成)。溴二甲基苯基锗烷与铬原子的金属配体共缩合,然后与萘二甲酸锂还原偶联,得到digermane络合物24。此外,该非桥接的衍生物[双(trimethylgermyl-η 6 -苯)M](M =铬,10D ; V,11 •),[(trimethylgermyl-η 6 -苯)(η 6 -苯)铬(10米)和[双(三苯锗-η
