Ferromagnetism and Chirality in Two-Dimensional Cyanide-Bridged Bimetallic Compounds
The combination of hexacyanoferrate(III) anions, [Fe(CN)6]3-, with nickel(II) complexes derived from the chiral ligand trans-cyclohexane-1,2-diamine (trans-chxn) affords the enantiopure layered compounds [Ni(trans-(1S,2S)-chxn)2]3[Fe(CN)6]2·2H2O (1) and [Ni(trans-(1R,2R)-chxn)2]3[Fe(CN)6]2·2H2O (2)....

Summary: | The combination of hexacyanoferrate(III) anions, [Fe(CN)6]3-, with nickel(II) complexes derived from the chiral ligand trans-cyclohexane-1,2-diamine (trans-chxn) affords the enantiopure layered compounds [Ni(trans-(1S,2S)-chxn)2]3[Fe(CN)6]2·2H2O (1) and [Ni(trans-(1R,2R)-chxn)2]3[Fe(CN)6]2·2H2O (2). These chiral systems behave as ferromagnets (T c = 13.8 K) with a relatively high coercive field (H c = 0.17 T) at 2 K. They also exhibit an unusual magnetic behavior at low temperatures that has been attributed to the dynamics of the magnetic domains in the ordered phase. |
