Study of the magnetic properties of the FeTiF_6 - 6 H_2O single crystal has shown that this compound is a two-dimensional antiferromagnet with a N e el temperature of T_N = 8 K and its magnetic moment anisotropy attains 7000% at a temperature of T = 4.2 K. The Mossbauer spectroscopy data unambiguously indicate the paramagnetic state of iron cations in the temperature range of 4.2-300 K. However, a sharp change in the difference between the quadrupole doublet linewidths at 10 K has been observed, which is consistent with the temperature of magnetic ordering. It has been suggested that the long-range magnetic order is established in the crystal through the formation of the exchange coupling revealed by the electron spin resonance measurements on the oriented single crystals.
