[Ag(η-CH₂CH₂)₃]⁺ is a prototypical metal–olefin complex displaying cation–π interactions. Herein, we describe the through-space magnetic response to better understand the influence of the metallic center on the organic ligands. The analysis reveals the short- and long-range anisotropic effects produced by Ag⁺, which influence the C₂H₄ ligands.
