Herein we report the first examples of single-molecule magnet (SMM) behaviour in = 1/2 Ni(iii) complexes. We find that low-spin 3d -[Ni(cyclam)(X)]Y complexes (cyclam = 1,4,8,11-tetraazacyclotetradecane; X and Y are singly charged anions) exhibit field-induced slow relaxation of magnetization for O-donor axial ligands (nitrate) but not for N-donor variants (isothiocyanate). Experimental and electronic structure computational investigations indicate that intrinsic spin polarisation of low-spin Ni(iii) is modulated significantly by local coordination geometry and supramolecular interactions.
