摘要：
We have studied the nature of magnetic ordering in the molecular magnet Mn[Fe(CN)(6)](2/3)center dot zH(2)O by employing dc magnetization and neutron diffraction techniques. A ferrimagnetic coupling of Mn2+ (S = 5/2) spins and the Fe3+ (S = 1/2) spins is found for the compound. The magnetic Bragg scattering in the neutron diffraction patterns is masked by a large diffuse scattering arising due to the structural disorder in the compound. The results of Reverse Monte Carlo simulations of neutron diffraction data show that around the coordinated oxygen atoms (located at the 24e crystallographic sites with [Fe(CN)(6)] vacancies), there are formations of small clusters of non-coordinated oxygen atoms.
