Tetranuclear [Ni4(CO3)4(pyridine)8·Na]Cl·pyridine·H2O compound with unusual square-planar geometry was obtained via spontaneous fixation of atmospheric CO2 and its conversion into carbonate bridging ligands. This compound exhibits a slow relaxation of the magnetization caused by a spin-glass behaviour. © 2021 Elsevier B.V.
