News from FeC : The title ternary rare‐earth compounds contain planar (magnetic) Fe 6 clusters interlinked by Fe(C 2 ) 3 units to form polymeric carboferrate complexes (see structure; red Fe, black C). The Fe 6 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 FeFe, polar dative ligand (C 2 )→metal (Fe), and Fe→RE interactions.
