Sensitive molecular scaffold : The exceptional π‐electron‐acceptor strength of HAT(CN) 6 renders it an excellent colorimetric halide sensor. It engages in multisite anion interactions, namely, both charge‐transfer and anion–π, in solution and the solid state. The halide ions are the driving elements for the spontaneous self‐assembly of the sandwich‐like complexes through η 2 ,η 2 ‐charge‐transfer contacts.
