Treatment of bis[bis(trimethylsilyl)amino]germanium(II) with elemental sulfur or selenium affords high yields of the corresponding monosulfide [(Me3Si)2N]2GeS and selenide [(Me3Si)2N]2GeSe, respectively. The crystalline products have now been shown to be cyclic dimers with (GeS/Se)2 four-membered rings by X-ray single crystal structure analysis. The crystal structure of (triphenylphosphine)gold(I) bis(trimethylsilyl)amide (Ph3P)Au-N(SiMe3)2 has also been determined. The molecule is a monomer with a tricoordinate nitrogen atom in a planar configuration [Si2NAu]. The compound does not undergo insertion of the bis[bis(trimethylsilyl)amino]germylene.
