Abstract The internal magnetic field (H n ) at57Fe nucleus was investigated for the mixed crystals, NBu4[Fe(II) x Mn(II)1-x Cr(III) (ox)3] (x=0.03−1) and NBu4[Fe(II) x Ni(II)1-x Fe(III)(ox)3]) (x=0−1) using Mössbauer spectroscopy, where NBu4/+=tetra(n-butyl)ammonium ion and ox2−=oxalate ion. With the decrease ofx, the direction ofH n at Fe(II) in NBu4[Fe(II) x Mn(II)1-x Cr(III)(ox)3] changed gradually from parallel to perpendicular, to the honeycomb layers consisting of an alternate array of the bivalent and tervalent ions through ox2− ligands. A variation of ca. 50° in direction was observed for theH n at Fe(III) in NBu4[Fe(II) x Ni(II)1-x Fe(III)(ox)3].
