Metallkomplexe mit anionischen Liganden von Elementen der 4. Hauptgruppe. XI. Substitutionsreaktionen der Trichlorgermid- und Trichlorstannid-Ionen an Metalltrifluorphosphin-Komplexen

Metal Complexes with Anionic Ligands of Main Group IV Elements. XI. Substitution Reactions of Trichlorogermide and Trichlorostannide Ions with Metaltrifluorophosphine Complexes The photochemical reactions of SnCl₃]^? in THF with the metal(0)-trifluorophosphine complexes of Ni, Fe, and Mo result in Ni(PF₃)₃SnCl₃]^?, Fe(PF₃)₃(SnCl₂]^?, and Mo(PF₃)₅SnCl₃]^?. GeCl₃]^?, in substitution reactions not as reactive as SnCl₃]^?, does react under similar conditions with Fe(NO)₂(PF₃)₂ only, to yield Fe(NO)₂(PF₃)GeCl₃]^?. With CpMn(PF₃)₃ (Cp = h⁵-C₅H₅) by the intermediatly formed CpMn(PF₃)₂THF both substitution derivatives CpMn(PF₃)₂ECl₃]^? (E = Ge, Sn) are found. The metallate(0) complexes are isolated as As(C₆H₅))₄]⁺- and N(C₂H₅)₄]⁺ -salts; the i.r.- and ¹⁹F-n.m.r.-spectra are reported.
