In order to explore the distinctive properties of these bilayer-type honeycomb layered oxides, a preliminary MD simulation was conducted by Sau using a previously reported force field, with interaction parameters similar to those of Na 2 Ni 2 TeO 6 . During this simulation, the polyhedral layers were held fixed at their centers to prevent any bending. Interestingly, the theoretical simulation successfully confirmed the formation of these bilayer structures using the predefined force field.
