文摘

In the presence of Cd(ClO₄)₂ and a base, a new mixed N,S-donor alkylthiolate ligand supported both carbonate formation from atmospheric CO₂ and the self-assembly of a novel bicapped puckered (CdS)₆ molecular wheel. The remarkable stability of the complex was demonstrated by slow intermolecular ligand exchange on the ²J(HH) and J(^111/113Cd¹H) time scales at elevated temperature. Both CO₂ and the base were required to convert amorphous 鈥淐dLClO₄鈥?precipitated in the absence of air to the carbonate complex. The complex shares structural features with the 味-carbonic anhydrase class associating cadmium(II) with the biogeochemical cycling of carbon and is the first structurally characterized carbonate complex of any metal involving an alkylthiolate ligand.
