The electron paramagnetic resonance of divalent Mn2+ions in the Tutton salt ZnTl2(SeO4)2· 6H2O single crystals has been observed at room temperature and liquid nitrogen temperature using X-band microwave frequency. The Mn2+has been found to substitute for Zn2+exhibiting two magnetically inequivalent complexes. The EPR spectra have been analyzed using the spin-Hamiltonian appropriate for rhombic symmetry.
