Abstract
Silber-Fluor-Clusterverbindungen AgnFm(0 ≦ m ≦ n, n ≥ 2) lassen sich durch Verdamp-fen von Silberatomen in mit SF6 angereichertes Argongas erzeugen. Die Massenspcktren der Kationen, die durch ElektronenstoBionisation erhalten werden, zeigen die relative Stabilitiit der verschiedenen Spezies. Es zeigt sich, daB dic Stabilitat bis zu relativ hoher Fluorierung durch die vethigbare Anzahl von Ag-Valenzelektronen bestimmt ist, wenn angenommen wird, daB jedes Fluoratom eines dieser Elektronen aufnimmt. Dieser Refund stiitzt die Annahme der Existenz eines von negativ geladenen Liganden umgebenen metallischen Kerns. Ein analoges Verhalien zeigen die Eigenschaften von kristallinem Ag2F.
Silver-fluorine cluster compounds AgnFm(0 ≦ m ≦ n, n ≥ 2) were produced by evapor-ation of silver into an argon atmosphere enriched with SF6 . The mass spectra of the cations, resulting from the subsequent electron impact ionization, reflect the relative stabilities of the various species. It turns out that up to rather high degree of fluorination these are determined by the available number of Ag valence electrons (if it is assumed that each F atom "consumes" one of these electrons). This suggests the existence of a metallic core, surrounded by negatively charged ligands, in analogy to the properties of crystalline Ag2F.
