(Ca7N4)[Mx] (M=Ag, Ga, In, Tl): Linear Metal Chains as Guests in a Subnitride Host

Abstract: Eine gemischtvalente Subnitrid‐Wirtstruktur mit parallelen Kanälen (${{{\rm {\rm Ca}}{{2+\hfill \atop 3\hfill}}}}$${{{\rm {\rm Ca}}{{1.5+\hfill \atop 4\hfill}}}}$${{{\rm {\rm N}}{{3- \hfill \atop 4\hfill}}}}$) lagert leicht Ketten aus metallischen Gastatomen ein (siehe Abbildung; Ca2+ orange, Ca1.5+ rot, N grün, M schwarz). Diese inkommensuraten Gäste aus linearen, äquidistanten Metallketten (M=Ag, Ga) oder entsprechenden Fragmenten (M=In, Tl) wechselwirken nur schwach mit ihrem Wirt.

“…Such kinds of phases represent a dispersion of a salt in a metallic environment and can be seen as a salt in a sea of metal 16. Subnitrides of the alkaline earth metals can also serve as hosts for less electropositive metals such as, for example, in [Ca 7 N 4 ]M x where M is Ag, Ga, In or Tl 17. Edge‐ and corner‐sharing [Ca 6 N] octahedrons form the host, and linear M x metal chains are guests in this framework.…”

“…Besides Sr 2 N some other subnitrides, Sr 4 N 3 [18] and Ca 7 N 4 M x , [20] have already been discussed, denoting the subvalent alkaline earth metal AE 1.5 + . Our research on subvalent alkaline earth compounds and their chemical bonding will be continued.…”

“…Neutrale Netzwerke aus verknüpften Ca6N‐Oktaedern können z. B. als Wirt für lineare Ketten von Metallatomen dienen 6). Die Aufteilung in Gast und Wirt kann zu einer charakteristischen eindimensionalen Ordnung der Struktur führen.…”
