Abstract
Magnetic ordering phenomena in mixed-metal assemblies {NBu4Fe(II)M(II I)(ox)3!}3 infinity (M=Cr (1), Fe (2)) were studied by using Fe-57 Moe ssbauer spectroscopy, where NBu4+=tetra(n-butyl) ammonium ion, ox2-=ox alate ion. Nuclear Zeeman splittings were observed in the Moessbauer s pectra of both 1 and 2 at low temperatures (below 10 K for 1 and 41 K for 2), which indicated the occurrence of three-dimensional magnetic o rdering in these complexes under zero applied field.
