FeCNFe
FeCNFe is a shorthand used in inorganic chemistry to denote a dinuclear iron cyanide core in which two iron centers are linked by cyanide ligands, forming an Fe–CN–Fe motif. It occurs as a constituent unit in cyanide-bridged coordination compounds and in Prussian blue and related analogues, where such bridges help connect metal centers into extended lattices.
In these motifs, each iron center is typically octahedrally coordinated, sharing a cyanide carbon with the
Synthesis and occurrence: FeCNFe units can arise during assembly of cyanide-bridged materials from iron salts and
Properties: The cyanide bridge provides superexchange pathways that influence magnetic behavior, often yielding antiferromagnetic or ferrimagnetic
