Magnetic properties of the organic conductor {kappa}-(BETS){sub 2}Mn[N(CN){sub 2}]{sub 3} above and below the temperature of the metal-insulator transition that occurs at T{sub MI} Almost-Equal-To 25 K are studied by {sup 1}H NMR. The proton spectrum is shown to be determined by the static dipolar fields from Mn{sup 2+} localized moments, while the {sup 1}H spin-lattice relaxation is dominated by fluctuating fields from Mn{sup 2+} electrons. The NMR data, both static (the spectra) and dynamic (the spin-lattice relaxation), indicate the freezing of Mn{sup 2+} moments into a short-range or an incommensurate long-range antiferromagnetic order below T{sub MI}.
