Abstract

Two isostructural nanosized coordination cages of formula [M^II₄SO₂TCA(μ₄-OH₂)]₆TATB₈·nS (M = Co or Ni, SO₂TCA = sulfonylcalix[4]arene, TATB = 4,4′,4′′-s-triazine-2,4,6-triyl-tribenzoate trisanion, S are solvent molecules) were obtained following a three-components strategy, using two different synthetic methods, leading to face-panelled octahedral coordination cages. The compounds were thoroughly analysed from a structural point of view, and for M = Co, the adsorption properties were measured, revealing a high surface area (SA = 742 m² g⁻¹) and a large CO₂ uptake for these types of compounds.
