作为[NiFe]氢化酶活性位点的模型，合成了一个双核镍钌配合物[Ni(xbsms) Ru(CO)(2)Cl-2]并对其进行了表征。三维结构显示，在方形平面双硫醚-二硫酯环境中，镍中心通过Ni(mu-SR)(2)Ru桥连接到钌部分。该络合物通过电还原N，N-二甲基甲酰胺中的弱酸性Et3NH+离子催化析氢，因此是第一个功能性的[NiFe]氢化酶的生物启发模型。
As a model of the active site of [NiFe] hydrogenases, a dinuclear nickel - ruthenium complex [Ni(xbsms) Ru(CO)(2)Cl-2] was synthesized and fully characterized. The three-dimensional structure reveals a nickel center in a square-planar dithioether-dithiolate environment connected to a ruthenium moiety via a Ni(mu-SR)(2)Ru bridge. This complex catalyzes hydrogen evolution by electroreduction of the weakly acidic Et3NH+ ions in N,N-dimethylformamide and is therefore the first functional bioinspired model of [ NiFe] hydrogenases.
