<jats:title>Abstract</jats:title><jats:p>We describe the syntheses, solid‐state structures, and magnetic properties of lanthanide(III)‐tris(bis(heterocyclo)methanides) [(THF)M{(NCOC<jats:sub>6</jats:sub>H<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>CH}<jats:sub>3</jats:sub>], with M=Tb (<jats:bold>1</jats:bold>), Dy (<jats:bold>2</jats:bold>), Ho (<jats:bold>3</jats:bold>), and Er (<jats:bold>4</jats:bold>), respectively. The corresponding lanthanide bis(trimethylsilyl)amides have been prepared as starting materials to deprotonate the neutral bis(benzoxazol‐2‐yl)methane ({NCOC<jats:sub>6</jats:sub>H<jats:sub>4</jats:sub>}<jats:sub>2</jats:sub>CH<jats:sub>2</jats:sub>) at the central methylene bridge to generate the monoanionic ligand. In the course of this investigations the hitherto unknown holmium tris(bis(trimethylsilyl)amide) is communicated in here. X‐ray diffraction data of <jats:bold>1</jats:bold>–<jats:bold>4</jats:bold> demonstrate an almost planar ligand with metal coordination in an <jats:italic>N</jats:italic>,<jats:italic>N</jats:italic>'‐chelating fashion. Different to their d‐metal analogous the magnetic data of the f‐metal complexes presented here show no single‐molecule magnet (SMM) properties.</jats:p>
