A T‐arrangement of two benzene rings contributes—aside from H‐bridges—to the stabilization of a 2:1 adduct of the molecular receptor 2 with [Pt(NH3)4]2⊕ in the solid state (X‐ray structure analysis); in [D6]acetone only a 1:1 adduct is present (1H‐NMR). With the same cation, 1 forms only 1:1 adducts in solution and in the solid state. Thus, small changes in the ligands can drastically alter its bonding properties (1, R  H; 2, R  Me). (Figure Presented.)
