A novel two-dimensional honeycomb-like bimetallic iron(III)–nickel(II) cyanide-bridged magnetic material [Ni(cyclam)]3[Fe(CN)6]2·nH2O(cyclam = 1,4,8,11-tetraazacyclodecane)

The 2D honeycomb-like layered iron(III)–nickel(II) cyanide-bridged complex [Ni(cyclam)]3[Fe(CN)6]2·nH2O exhibits ferromagnetic intralayer and antiferromagnetic interlayer interactions; above 3 K the magnetic properties are typical of a metamagnet with Hc = 5000 G, whereas below 3 K a canted structure is formed, leading to a long range ferromagnetic ordering.
