We report a rapid and facile route to the synthesis of a family of Mn-III monomers of general formula [(MnF3)-F-III(H2O)(L1-6)]xH(2)OyMeOH [L-1 = 2,2-bipyridyl, x = 2, y = 0 (1); L-2 = 1,10-phenanthroline, x = y = 0 (2); L-3 = 6-methyl-2,2-dipyridyl, x = y = 0 (3), L-4 = 4,4-dimethyl-2,2-dipyridyl, x = 2, y = 0 (4), L-5 = 5,5-dimethyl-2,2-dipyridyl, x = 0, y = 0.5 (5); L-6 = 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 cm(-1) in 2 to -4.02 cm(-1) in 5), while multi-frequency/high-field EPR spectroscopic measurements and subsequent simulations gave similar values for complexes 1 (-4.25 cm(-1)), 2 (-4.03 cm(-1)), 4 (-3.90 cm(-1)) and 5 (-4.04 cm(-1)). The terminal Mn-F vibrational stretches in 1-6 have been probed using Raman spectroscopy.
