Electron paramagnetic resonance of Mn2+ in La2Zn3(NO3)12 • 24H2O single crystals is studied at ≈ 9.45 GHz. Mn2+ substitutes for Zn2+ sites. The spin-Hamiltonian parameters are evaluated at 290 K. The superposition model has been applied to the zero-field splitting parameter D for Mn2+ in Ce2Mg3(NO3)12 • 24H2O and La2Mg3 (NO3)12 • 24D2O at both sites. It is shown that the calculated values of D are in agreement with the experimental values if local relaxation effects are taken into account.
