Nickel(II) complexes based on L-amino-acid-derived ligands: synthesis, characterization and study of the role of the supramolecular structure in carbon dioxide capture.

ABSTRACT: The formation of the symmetrical μ₃-carbonate-bridged self-assembled trinuclear Ni^II complex Na₂{[Ni(LO)₂(H₂O)]₃(μ₃-CO₃)} (LO is the carboxylate anion of a L-tyrosine derivative), involves atmospheric CO₂ uptake. The asymmetric unit of the complex comprises an octahedral coordination for the Ni^II with two L-tyrosine-based ligands, a water molecule and one O atom of the carbonate bridge. The Ni₃-μ₃-CO₃ core in this compound is the first reported of this kind according to the Cambridge Structural Database (CSD). The supramolecular structure is mainly sustained by hydrogen bonds developed by the phenolic functionality of the L-tyrosine moiety of one li
