Abstract

Mono- and tetra-deprotonated 2-methylresorcinarene anions (1 and 2) as their trans-1,4-diammoniumcyclohexane (TDAC)²⁺ inclusion complexes are reported. The mono-anion forms a fully closed dimeric capsule [1·H₂O·MeOH]₂²⁻ with a cavity volume of 165 Å³ and (TDAC)²⁺ 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 2a and 2b with a 50 : 50 ratio in the crystal lattice.
