We report a rapid and facile route to the synthesis of a family of MnIII monomers of general formula [MnIIIF3(H2O)(L16)]xH2OyMeOH [L1 = 2,2′-bipyridyl, x = 2, y = 0 (1′); L2 = 1,10′-phenanthroline, x = y = 0 (2′); L3 = 6-methyl-2,2′-dipyridyl, x = y = 0 (3), L4 = 4,4-dimethyl-2,2′-dipyridyl, x = 2, y = 0 (4), L5 = 5,5′-dimethyl-2,2′-dipyridyl, x = 0, y = 0.5 (5); L6 = 5-chloro-1,10-phenanthroline, x = y = 0 (6)]. Magnetic susceptibility and magnetisation experiments have been employed to elucidate the D tensor for each family member (ranging from 3.01 cm1 in 2′ to 4.02 cm1 in 5), while multi-frequency/high-field EPR spectroscopic measurements and subsequent simulations gave similar values for complexes 1′ (4.25 cm1), 2′ (4.03 cm1), 4 (3.90 cm1) and 5 (4.04 cm1). The terminal MnF vibrational stretches in 1′6 have been probed using Raman spectroscopy.
