The neutral technetium(V) phosphoraneimine complex [TcNCl 2 (Ph 2 PNH) 2 ] is formed when (Bu 4 N)[TcOCl 4 ] reacts with Me 3 SiNPPh 3 in dichloromethane. Distances of 2.078(4) and 2.102(4) Å have been found between Tc and the neutral triphenylphosphoraneimine ligands. The Tc‐N‐P angles are 133.7(3) and 134.8(3)°. The terminal nitrido ligand is formed by decomposition of an additional molecule of Me 3 SiNPPh 3 . The protons which are used for the protonation of the organic ligands are released during the decomposition of CH 2 Cl 2 . The same reaction yields the [TcNCl 4 ] — anion when it is performed in acetonitrile.
