Fe(NCMe)‐Komplexe von chiralen Tripodliganden mit drei verschiedenen Donorgruppen: Dynamik und Struktur

Fe(NCMe) Complexes of Chiral Tripod Ligands Bearing three Different Donor Groups: Dynamics and Structure Chiral tripod ligands [tripod = CH3C(CH2PR2)(CH2PR′2)(CH2‐PR′′2), 1a–d] with three different donor groups react with Fe(NCMe)6(BF4)2 to yield the complexes tripodFe(NCMe)3(BF4)2 (2a–d). These complexes show an idealized octahedral coordination based on a facial coordination of the tripod ligand. The asymmetry of the chiral tripod ligands a–d induces a differentiation of the remaining coordination sites at iron. The structure and the dynamic behaviour of the compounds 2a, b is elucidated by X‐ray structural analyses and 2D‐NMR techniques.
