The First Coordinatively Saturated, Quadruply Stranded Helicate and Its Encapsulation of a Hexafluorophosphate Anion.

Abstract

Incarcerated in a helical prison: The encapsulation of a PF₆⁻ ion within a quadruply stranded helicate (shown schematically) results from the self‐assembly of four molecules of 1,4‐bis(3‐pyridyloxy)benzene and two Pd^II ions. This represents not only the first example of a coordinatively saturated quadruple helicate, but also the first example of the encapsulation of a complex anion by a helicate.
