Efficient fixation of atmospheric CO2 as carbonate by lanthanide-based complex via synergistic effect of zinc ion

Abstract

Reactions of [Zn(L)(H₂O)] precursor and EuCl₃ with the aid of CO₃²⁻ ions derived from atmospheric CO₂ affording an unusual heteropolynuclear cluster [Zn₄L₄Eu₄(CO₃)₆]·EtOH. In the core of the cluster, four hetero-binuclear [ZnLEu] units linked by six CO₃²⁻ anions forms a well defined [Zn₄Eu₄] skeleton with good planarity, which plays an important role in stabilizing the cluster.
