Description

The title ternary rare-earth compounds contain planar (magnetic) Fe6 clusters interlinked by Fe(C2)3 units to form polymeric carboferrate complexes (red Fe, black C). The Fe6 clusters can be regarded as fragments of γ-Fe and binary iron carbides. The chemical bonding situation in the ternary compounds is characterized by covalent Fe-Fe, polar dative ligand (C2)→metal (Fe), and Fe→RE interactions.
