Summary
Single ion magnet behaviour is reported for a mononuclear Mn(III) ion with tridentate Schiff-base ligands which exhibits a tetragonal Jahn-Teller elongation along the Namine-Mn-Namine axis and crystallises with two crystallographically distinct Mn(III) cations (unit A and unit B). While magnetic measurements show a large and negative axial zero-field splitting (D = -4.73 cm-1), HF-EPR reveal two distinct large axial Ds (D = -4.60 cm-1 for unit A and D = -4.18 cm-1 for unit B), thus resulting in the largest D known to date for a Mn(iii) single ion magnet. AC magnetic measurements at 2000 Oe allowed determination of the energy barrier for spin reversal (10.19 K) and spin reversal relaxation time (1.476 [times] 10-6 s) for the Mn(III) ion. Computational studies were used to characterise the electronic structure and substantiate the zero field splitting in the Mn(III) complex.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\n
