Zusammenfassung

The reaction of [LWCl] (3) [L=N(CH2CH2NiPr)3] with LiE/SiMe3)2 (E=P, As, Sb) yields the novel, neutral pnictido-bridged complexes [LW=E=WL] (5-7). By following the reaction, which starts from the LiP/SiMe3)2 derivative, by 31P NMR spectroscopy, the formation of an intermediate with a terminal pnictido ligand can be ruled out. The paramagnetic complexes 5-7 are comprehensively spectroscopically ...
