Resum

A series of Ni(II) trinuclear complexes, [Ni3(sala-X)6] (sala-X = o-[(p-X-phenylimino)methyl]phenol; X = Br 1-Br, Me 1-Me and OMe 1-OMe), have been prepared and fully characterised. X-ray crystallographic studies reveal that the complexes are composed of three face-sharing octahedral Ni(II) metal ions bridged by the phenoxide oxygens of the sala-X ligands. Magnetic studies indicate that the magnetic Ni(II) centres are ferromagnetically coupled with the substituent group having only a minor impact on the magnitude of coupling. AC susceptibility studies show no evidence of single-molecule magnet behaviour. DFT calculations also support ferromagnetic coupling with smaller Ni-O-Ni angles leading to slightly larger coupling constants in line with previous studies.
