    Description / Table of Contents: Metal Complexes with Anionic Ligands of Main Group IV Elements. XI. Substitution Reactions of Trichlorogermide and Trichlorostannide Ions with Metaltrifluorophosphine ComplexesThe 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.
    Notes: Unter UV-Bedingungen in THF liefern [SnCl3]--Ionen mit den Metall(0)-trifluorphosphinen von Nickel, Eisen und Molybdän die Metallat(0)-Komplexe [Ni(PF3)3SnCl3]-, [Fe(PF3)3(SnCl3)2]2- und [Mo(PF3)5SnCl3]-. Hingegen bildet das bei Substitutionsreaktionen hinter dem [SnCl3]-. Ion zurückstehende [GeCl3]-.-Ion unter ähnlich drastischen Bedingungen lediglich mit Fe(NO)2(PF3)2 das Monosubstitutionsprodukt [Fe(NO)2(PF3)GeCl3]-. Aus CpMn(PF3)3 (Cp = h5-C5H5) sind über den intermediär gebildeten Komplex CpMn(PF3)2THF beide Substitutionsderivate [CpMn(PF3)2ECl3]- (E=Ge, Sn) leicht zugänglich. Die Metallatkomplexe werden als [As(C6H5)4]+- bzw. [N(C2H5)4]+ -Salze isoliert; ihre IR- und 19F-NMR-Daten werden mitgeteilt.
