Anionic or neutral? the charge of Ni8 cubes in metal–organic framework compounds
The cubic SBU Ni8X6L6 (X = OH−/H2O, L = ligand) in MOFs has so far been described as neutral in the literature. We investigated by detailed DRIFTS measurements and exchange reactions whether it shows anionic character, as observed in complexes.
