Antiferro- to ferromagnetic crossover in diphenoxido bridged (Ni2MnII)-Mn-II complexes derived from N2O2 donor Schiff base ligands

Three new trinuclear Ni-II-Mn-II complexes have been synthesized using three different 'metalloligands' [NiL1], [NiL2] and [NiL3] derived from the Schiff bases H2L1 = N,N'-bis(salicylidene)-1,3-pentanediamine, H2L2 = N,N'-bis(salicylidene)-1,3-propanediamine and H2L3 = N,N'-...

Theoretical calculations have been performed in order to understand the effect of structural parameters that can tune the magnetic properties of this type of complexes such as small differences in the Ni-O-Mn angle and/or slight variations in intermolecular contacts within the crystal.
