(A) Schematic of Cl–π interactions. The interaction is defined by the θ angle of the Cl atom relative to the plane of the ring. (B) Two geometries found in Cl–π interactions: (i) face-on and (ii) edge-on geometries. The geometry is defined by the difference between two distances, which are between the Cl atom and the centroid or the nearest atom of the aromatic ring.
