Tetranuclear cyanide rhenium(I)–copper(I) coordination compounds were synthesized in the course of simple one-pot reactions in mild conditions. A new class of mixed-metal compounds based on rhenium(I) clusters that are comprised of the pseudo-rhombic-shaped {Re₂Cu₂(μ-CN)₄} unit were found. Two kinds of geometries adopted by the self-assembled cyclic clusters are observed, both of which can be described as approximately block-like overall geometries with different coordination modes. The unique polynuclear structure {ReCu(CH₃CN)(μ-CN)₂(CO)₂(PPh₃)₂}_n can be formed under the reaction conditions. Presented compounds were characterised by single crystal X-ray diffraction and spectroscopic studies.

在温和的条件下，通过简单的一锅反应即可合成四核氰化物rh（I）-铜（I）配位化合物。发现了一类新的基于rh（I）团簇的混合金属化合物，该化合物由假菱形的{Re ₂ Cu ₂（μ-CN）₄ }单元组成。观察到自组装循环簇采用的两种几何形状，它们都可以描述为具有不同协调模式的近似块状总体几何形状。独特的多核结构{ReCu（CH ₃ CN）（μ-CN）₂（CO）₂（PPh ₃）₂ } _n可以在反应条件下形成。通过单晶X射线衍射和光谱研究表征了所提出的化合物。
