Abstract: | The neutral technetium(V) phosphoraneimine complex [TcNCl2(Ph2PNH)2] is formed when (Bu4N)[TcOCl4] reacts with Me3SiNPPh3 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 Me3SiNPPh3. The protons which are used for the protonation of the organic ligands are released during the decomposition of CH2Cl2. The same reaction yields the [TcNCl4]— anion when it is performed in acetonitrile. |
