    • Wasfi et al. described the anion [Fe4Cu2W 18O70H6]10, ref.[13, where a tetrametallic cluster Fe2Cu2 is sandwiched between two moieties FeW9. This compound was obtained by a one-pot synthesis and even in this case, Fe atoms still occupied the internal positions in the central cluster. So, the idea to get Fe atoms in the external positions is very important. For the first time we have FeIII on the external sites and coordinated to H2O molecule, its behaviour can be compared with noncoordinated Fe111 when the Fe atoms are in internal positions, case known and described until now

    • One must take into account that for ionic that remains unchange (the total number of atoms is the same in the two complexes Ni2As4 and Fe2-Ni2As4), the overall electrical charge increase for more than 20 %, which is very significant if one considers the change in charge density that follows.

    • In Ni2As4, junctions between the two tungstic fragments, As 2W15O56]12- and the equatorial metallic cluster Na2Ni2O16 is from αααα-type. The replacement of the two Na+ by two Fe3+ is accompanied by structural reorganization, which leads to a new type of junction between [As2W15O56] 12- fragments and the new equatorial cluster, Fe2Ni 2O16, a αββα-type junction
