Fe(NCMe) 2+ 3Complexes of Chiral Tripod Ligands Bearing three Different Donor Groups: Dynamics and Structure Chiral tripod ligands [ tripod = CH 3 C(CH 2 PR 2 )(CH 2 PR′ 2 )(CH 2 ‐PR′′ 2 ), 1a–d ] with three different donor groups react with Fe(NCMe) 6 (BF 4 ) 2 to yield the complexes tripod Fe(NCMe) 3 (BF 4 ) 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.
