Abstract

Exposure of the dinuclear hydroxo complex {[La(tpen)(mu-OH)]2(mu-eta1:eta1OTf)}OTf3 to air results in the immediate uptake of atmospheric CO2 affording an unusual hexanuclear lanthanum carbonato complex in which the carbonate anions are ligated in a mu3-eta1:eta1:eta2 and mu3-eta1:eta2:eta2 fashion.
