Abstract
Magneto-structural correlations in Mn( en)Ni(CN) 4 (en = ethylenediamine) (MENC) have been studied. The crystal structure of MENC was refined by Rietveld analysis of X-ray powder diffraction data; it is three-dimensional (3d) and is built up of [Mn( en)] 2+ cations with deformed octahedrally coordinated Mn(II) ( S = 5 / 2 ) atoms and [Ni(CN) 4] 2− anions containing square-planarly coordinated Ni(II) ( S = 0 ) atoms. The building species are linked by bridging μ 2 -cyano ligands. The characterization of magnetic properties confirmed the expected 3d nature of spin correlations by observing λ-like anomaly in specific heat at T c = 0.47 K . The resulting exchange interaction J / h c = − 0.12 cm −1 is somewhat smaller than that found in other complexes with the same type of exchange paths.
