Antiferromagnetic order at T-N = 23 K has been identified in Mn(III) F(salen), salen = H14C16N2O2, an S = 2 linear-chain system. Using single crystals, specific heat studies performed in magnetic fields up to 9 T revealed the presence of a field-independent cusp at the same temperature where H-1 NMR studies conducted at 42 MHz observed dramatic changes in the spin-lattice relaxation time, T-1, and in the linewidths. Low-field (less than 0.1 T) magnetic susceptibility studies of single crystals and randomly-arranged microcrystalline samples reveal subtle features associated with the transition.
