π-Stacking of [Pt(2,2'-bipyridine)(ethylenediamine)]²⁺ as its Hexafluorophosphate Salt

The crystal structure of (2,2′-bipyridine-N,N')(ethylenediamine-N,N')platinum(II) bis(hexafluorophosphate), [Pt(C₂H₈N₂)(C₁₀H₈N₂)](PF₆)₂, [Pt(bpy)(en)](PF₆)₂, contains π-bpy-stacked columns of platinum complex cations. The bpy ligands are stacked keeping van der Waals contacts although the crystal exhibits essentially the same ³π–π^* emission spectrum as that in dilute solution.
