The different tendencies of dinuclear azacryptates the m-CH2C6H4CH2 and 2,5-furano-spaced hosts L1 L2 to catalyse CO2 uptake-reactions within these sterically-protected host cavities are examined. Bridging methylcarbonates generated catalytically upon exposure methanol solutions L1, but not L2, di-transition cation cryptates atmospheric CO2. X-Ray crystallographic structures homodinuclear μ-carbonato both ligands μ-methylcarbonato with later first transition series cations reported. ESI-MS spectra show loss H2CO3 from in collision activation experiments.
