    Description / Table of Contents: Organophosphine-substituted Halogenogermylenes and -stannylenesHalogeno(di-tert-butylphosphino)germanium(II) and -tin(II) [(CH3)3C]2PMX (M = Ge, Sn; X = Cl, Br) are obtained by the reactions of triphenylphosphinedichloro- and -dibromogermylene, tindichloride and tri-tert-butylphosphinedibromostannylene with equimolar amounts of di-tert-butyl(trimethylsilyl)phosphine with elimination of chloro- and bromotrimethylsilane. Vibrational spectra of the new stable phosphine-substituted halogenogermylenes and -stannylenes are discussed in terms of coordination polymeric structures with bridging phosphino groups.
    Notes: Die Halogen(di-tert-butylphosphino)germanium(II)- und -zinn(II)-Verbindungen [(CH3)3C]2PMX (M = Ge, Sn; X = Cl, Br) entstehen bei den Umsetzungen von Triphenyldichlor- und -dibromgermylen, Zinn(II)-chlorid und Tri-tert-butylphophindibromstannylen mit Di-tert-butyl(trimethylsilyl)phosphin unter Abspaltung von Chlor- bzw. Bromtrimethylsilan. Für die neuen stabilen phosphinsubstituierten Halogengermylen und Halogenstannylene werden auf Grund schwingungsspektroskopischer Daten koordinationspolymere Strukturen mit verbrückenden Phosphinogruppen vorgeschlagen.
