Abstract
[M(bpy)3]q+ cations (bpy = 2,2′-bipyridine) are archetypical coordination entities containing chelating bidentate N,N′-donor ligands. Each propeller-shaped cation is chiral, existing as a Δ or Λ enantiomer. The supramolecular chemistry of [M(bpy)3]q+ cations in the crystal is dominated by cation-anion interactions and, to a lesser extent, weaker non-covalent interactions. Analysis of the data for [M(bpy)3]q+ salts in the Cambridge Structural Database (CSD) reveals a ubiquitous motif in which homochiral sheets of cations generate cavities for the accommodation of anions. A series of related and common motifs in the solid-state structures of [M(bpy)3]q+ salts has been identified. One of the commonest motifs comprises a hexagon of six cations with anions either in the center or lying above and/or below the centroid.
