    Tuneable Intramolecular Intermetallic Interactions as a New Tool for Programming Linear Heterometallic 4f−4f Complexes
    摘要:
    Statistical mechanics predicts that the design of pure organized heteropolymetallic chains of metal ions bound to linear receptors depends on controlled deviations from the mixing rule triangle E-MMj = 1/2 (triangle E-MMi + triangle E-mjmj), whereby triangle E-MiMj is the intramolecular intermetallic interaction between neighboring metal i and metal j along the receptor. A thorough investigation of linear polymetallic trivalent lanthanide triple-stranded helicates shows that such deviations are amplified by an increase in the nuclearity of the final complexes and are thus easily evidenced in the tetranuclear heterobimetallic helicates [La-4_Lu-y(y) (L6)(3)](12+) (y = 0-4). The chemical and physical origins of this unprecedented behavior are discussed together with its practical consequences for programming pure heteropolymetallic 4f-4f complexes.

    A new family of heterometallic catalysts based on trimetalated macrocyclic tris(salen) ligands and rare‐earth metals was prepared and structurally characterized. The LaZn3 system containing anionic ligands such as acetate plays a critical role in catalyzing the alternating copolymerization of cyclohexene oxide (CHO) and CO2 with a high proportion of carbonate linkages. Among the lanthanide metals,

In all, the dmp– ligands adopt exclusively the κ1O;κ1O′ bridging mode, the overall results indicating

    Hetero-multinuclear metal complexes are a promising class of compounds applicable to photoluminescence, magnetism, and catalysis. In this work, we have developed a synthetic method for hetero-tetranuclear metal complexes by combining advantage of site-selective redox switching and transformation. Firstly, a homo-tetranuclear CoII4 complex was converted to a mixed-valence CoIIICoII3 complex by site-selective
    杂多核金属配合物是一类很有前途的化合物,可用于光致发光、磁性和催化。在这项工作中,我们结合了位点选择性氧化还原转换和转化的优势,开发了一种异质四核金属配合物的合成方法。首先,通过位点选择性氧化将均四核 CoII4 配合物转化为混合价 CoIIICoII3 配合物,然后将其从 CoII 转移到 NiIII,形成异金属 CoIIINiII3 配合物。最后,通过在 CoIII 位点上的金属选择性还原合成了 CoIINiIII3 配合物。从CoII4复合物开始的整个过程中主要产物的基本结构框架是同构的。值得注意的是,CoIINiIII3 复合物不能通过配体、CoII 和 NiiII 的直接混合获得。
