Magnetic ionic liquids derived from hydrochloride methyl ester alanine amino acids (AA) and FeCl_{3} were synthesized in ethanol and their magnetic properties were investigated. Iron (III) chloride forms ionic liquid in ethanol at saturated concentrations by the transfer of Cl¯ anion from one molecule of FeCl_{3} to the other molecule with the creation of tetrachloro ferrate anion [FeCl_{4}]¯ as well as dimer [Fe_{2}Cl_{7}]¯. Raman scattering indicates that after addition of hydrochloride methyl ester alanine to ethanol solutions of FeCl_{3} increase the intensities of signal at the frequencies at 318 cm^{-1} and 380 cm^{-1} as markers for the presence of [FeCl_{4}]¯ and [Fe_{2}Cl_{7}]¯ complexes. The magnetization at room temperature showed in both samples a linear dependence on the applied magnetic field. On the other hand, in the Raman scattering experiments the magnetization is smaller for FeCl_{3} sample in the presence of methyl ester alanine.
