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(NH 3 ) 4 ] 2⊕ in the solid state (X‐ray structure analysis); in [D 6 ]acetone only a 1:1 adduct is present ( 1 H‐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).
