Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>An enantiomerically pure BINOL‐based bis(3‐pyridyl) ligand <bold>1</bold> assembles into a homochiral [Pd₄(<bold>1</bold>)₈] complex upon coordination to tetravalent Pd^II ions. The formation of this aggregate is templated by two tetrafluoroborate counterions that are encapsulated in two peripheral cavities. The resulting structure is a new structural motif for this kind of metallosupramolecular assemblies that arranges the palladium ions in a distorted tetrahedral fashion and forces ligand <bold>1</bold> to adopt two different conformations. Both phenomena are unique and cause an overall three‐dimensional structure that has another confined, chiral, and hydrophilic central cavity.</p> </abstract>
