Abstract

The diruthenium compound [Ru₂(O₂CMe) ₄]₃[Cr(CN)₆] contains two interpenetrating sublattices that behave like giant antiferromagnetically coupled moments with strong anisotropy. Preferred orientations of the total moment of each sublattice are determined from susceptibility measurements on a polycrystalline sample. In agreement with previous predictions, fits to the experimental magnetization indicate that the sublattice moments are aligned along cubic diagonals rather than cubic axis or edge diagonals. The parametrization of the sublattice susceptibility implies that the sublattice spin states are more deformed when aligned antiparallel.
