Nine complexes of type ML2 with M = Ni, Pd, Pt and L = X(CHCH)2BC6H5 (X = (CH3)2C, (CH3)2Si, (CH2)2) are described. The X-ray structural analysis of Ni[(CH3)2Si(CHCH)2BC6H5]2 and the 1H and 11B NMR spectra demonstrate a sandwich-type bis(η5-divinylborane)metal structure with C2 molecular symmetry. All complexes show exceptional thermal stability as compared to the corresponding bis(1,5-cyclooctadienyl)metal
九种类型为ML 2的配合物,其中M = Ni,Pd,Pt和L = X (CH = CH )2 BC 6 H 5(X =(CH 3)2 C,(CH 3)2 Si,(CH 2)2)进行了说明。Ni的X射线结构分析[(CH 3)2的Si(CHCH)2 BC 6 ħ 5 ] 2和1 H和11乙NMR谱表明夹心型双(η 5 -divinylborane)金属结构与C 2分子对称。与相应的双(1,5-环辛二烯基)金属配合物相比,所有配合物均显示出优异的热稳定性。在1 H NMR光谱中,在室温下观察到两个Pd配合物和Pt配合物两个配体相对于彼此的内部旋转。
Mn2(CO)10 produces the triple-decked complex (OC)3Mn(μ-L)Mn(CO)3 (III) where L is 2-ethyl-1-phenylborole. The analogous system I/[(C5H5)Fe(CO)2]2 inter alia yields the triple-decked sandwich complex (C5H5)Fe(μ-L)Fe(C5H5) (VI) and the borabenzene derivative (C5H5)Fe(2-CH3C5H4BC6H5) (VIII). The structures of the 30-electron compounds III and VI have been determined by X-ray analyses.
