Novel adducts of titanium, zirconium, and hafnium tetraazide with N‐donor ligands were obtained in quantitative yields from the corresponding metal fluorides [MF 4 ] by fluoride–azide exchange with Me 3 SiN 3 in acetonitrile solution in the presence of stoichiometric amounts of the corresponding N‐donor ligand. The polyazido adducts [(bpy)Ti(N 3 ) 4 ], [(phen)Ti(N 3 ) 4 ], [(bipy) 2 Zr(N 3 ) 4 ] 2 · bpy, and [(bipy) 2 Hf(N 3 ) 4 ] 2 · bpy were characterized by vibrational spectroscopy and single‐crystal X‐ray diffraction.
