Unusual Capping Chalcogenide Dependence of the Luminescence Quantum Yield of the Hexarhenium(III) Cyano Complexes [Re6(<i>μ</i>3-E)8(CN)6]4−, E2− = Se2− &amp;gt; S2− &amp;gt; Te2−

Abstract

Abstract Hexarhenium(III) clusters [Re6(μ3-E)8(CN)6]4− (E2− = S2−, Se2−, Te2−) are luminescent at room temperature with the emission quantum yield and lifetime in the order E2− = Se2− &amp;gt; S2− &amp;gt;&amp;gt; Te2− both in acetonitrile and water.
