Although metal-metal bonding is important in the chemistry of both solid-state intermetallic compounds and molecular species, the study of this bonding is limited by the compounds available and it is rarely possible to identify connections between these two areas. In this study, molecular intermetalloids [Ln(ReCp(2))(3)] (Ln = Sm, Lu and La) have been synthesized that contain lanthanoid metals bound only to transition metals. Although they are highly reactive species, such lanthanoid-core transition-metal-shell compounds can be stable in solution. They mimic the bonding situation of intermetallic compounds, as revealed by a direct comparison of molecular and solid state lanthanoid-transition metal bonding.
尽管金属-金属键合在固态金属间化合物和分子物种的化学中都很重要，但对这种键合的研究受到可用化合物的限制，而且通常很难确定这两个领域之间的联系。在这项研究中，合成了仅包含镧系金属与过渡金属结合的分子金属间化合物[Ln(ReCp(2))(3)]（Ln = Sm、Lu 和 La）。尽管它们是高反应性物质，但这种镧系元素核心-过渡金属壳化合物在溶液中可以稳定存在。它们模拟了金属间化合物的键合情况，这可以通过直接比较分子和固态镧系元素-过渡金属键合来揭示。
