高分辨率电喷雾电离质谱(HRESI-MS)是研究金属团簇在溶液中的稳定性的一种有效的手段[1,2],可用于研究团簇在溶液中的形成机理[3,4]。为此,我们利用水杨酸(sal)为配体,三乙醇胺(TEOA)作为辅助配体,合成了一例环状的稀土-铁簇合物[Ln4Fe4(TEOA)8(sal)4]·(CH3COOH)·(H2O)5(图1)。
3d-4f 金属簇合物由于其迷人的结构、有趣的性质和潜在的应用价值,一直以来受到广大研究者的关注[1-3]。同时具有较高的亲核性和良好的热稳定性,缺位多酸可以作为多齿无机配体与金属离子组装形成多酸保护的3d-4f 簇合物[4,5]。
近年来,尽管在炔基保护的金纳米团簇(Au NCs)分子的精准制备方面取得了不少进展(如:Na[Au25(C≡CPh)18]、Au36(C≡CPh)24、Au44(C≡CPh)28 和Au144(C≡CAr)60),但对炔基团簇的形成机理尚不清楚。

A novel heterobimetallic 2-dimensional layer complex,[FeⅢ(bpy)(CN)4]2MnⅡ2·2H2O [bpy=2,2-bipyridine](1)has been prepared by diffusing and its structure determined by single crystal X-ray diffraction.Th
AlCl3-CuCl-芳烃溶液在气体分离领域显示出很好的应用前景[1-2]。已有的研究大部分都集中于其在烷烃/烯烃、N2/CO分离过程中的应用[3]。鲜有公开文献报道该体系自身的化学组成及结构,尤其是Al物种的化学结构。而Al物种的化学结构与该体系在气体分离时的高选择性紧密相关,而要弄清其作用机理,那么获得体系中Al物种的化学信息则显得尤为必要。
