Supramolecular architectures featuring stereoisomeric cluster complexes of the [Re6(μ3-Se)8]2+ core

The [Re6(μ3‐Se)8]2+ core‐containing cluster complexes of the general formula [Re6(μ3‐Se)8(PEt3)4L2]2+ (both trans‐ and cis‐isomers) site‐differentiated with inert PEt3 and functional L ligands that are capable of hydrogen bonding or secondary (with respect to primary coordination with the cluster co...

Description
Summary:The [Re6(μ3‐Se)8]2+ core‐containing cluster complexes of the general formula [Re6(μ3‐Se)8(PEt3)4L2]2+ (both trans‐ and cis‐isomers) site‐differentiated with inert PEt3 and functional L ligands that are capable of hydrogen bonding or secondary (with respect to primary coordination with the cluster core) metal‐ligand coordination interactions have been prepared. The applications of such stereospecific cluster isomers as building blocks for supramolecular construction have been studied. A great variety of multicluster arrays mediated by intercluster hydrogen bonding or cluster ligand coordination with secondary metal ions have been obtained and structurally characterized. The findings from this research clearly establish the superior utility of these novel building blocks for the creation of structurally sophisticated architectures and possibly functional materials.
