چکیده

Mono- and tetra-deprotonated 2-methylresorcinarene anions ( and ) as their trans-1,4-diammoniumcyclohexane inclusion complexes are reported. The mono-anion forms a fully closed dimeric capsule [·H2O·MeOH]2(2-) with a cavity volume of 165 Å(3) and as the guest with an extremely high packing coefficient, PC = 84.2%, while the tetra-anion forms a close-packed structure with two structurally isomeric tetra-anions and with a 50 : 50 ratio in the crystal lattice.
