CHELATE COMPLEXES OF TRIPODAL, ALIPHATIC TRIISOCYANIDE LIGANDS

The distinct low‐field shift of the NMR resonance for the central methine proton of the ligand, which penetrates the deshielded region of the anisotropic sphere of the three NC bonds of the complexes 1 (M = Cr, W), suggested the assignment of the in configuration for this complex. The X‐ray structure analysis confirmed the assignment. The synthesis of 1 shows that aliphatic isocyanides with few framework atoms can also form chelate complexes with transition metals.
