L'octachlorodirhénate de potassium est un composé inorganique de formule K2Re2Cl8. Ce sel bleu foncé est connu comme un des premiers composés identifiés comportant une liaison quadruple entre ses centres métalliques. Bien que le composé n'ait aucune valeur pratique, sa caractérisation a été importante pour ouvrir un nouveau champ de recherche sur les complexes à liaison quadruple. (fr) Potassium octachlorodirhenate(III) is an inorganic compound with the formula K2Re2Cl8. This dark blue salt is well known as an early example of a compound featuring quadruple bond between its metal centers. Although the compound has no practical value, its characterization was significant in opening a new field of research into complexes with quadruple bonds. (en) 八氯合二铼酸钾，是一种含有四重键的配合物，化学式为K2[Re2Cl8]。它的结构由美国无机化学家弗兰克·阿尔伯特·科顿（F.A.Cotton）于1964年测定（阴离子结构如图所示）。分子轨道理论认为该离子的四重键可表示为σ2π4δ2，也就是包括一个σ键、两个π键和一个δ键。 (zh) |
