Abstract Congruent lithium niobate crystals doped with Mg and Fe are investigated by means of nuclear magnetic and electron paramagnetic resonances (NMR and EPR), X-ray structure and fluorescence analyses. It is shown that the low-symmetry complexes FeNb-MgLi are created at magnesium concentration above 4.5 mol.%.
