Synthese und Kristallstrukturen ternärer Phosphide und Arsenide des Rhodiums und Iridiums

Abstract: Inhaltsübersicht. Von acht neuen Verbindungen wurden Einkristalle durch Erhitzen der entsprechenden Elementgemenge in einer Bleischmelze gezüchtet und röntgenographisch untersucht. Ca 2 Ir 12 P 7 (a ϭ 9,512(1), c ϭ 3,923(1) Å ) ist ein weiterer Vertreter des Zr 2 Rh 12 P 7 -Typs, das Vorliegen von Mikrodomänen erforderte die Verfeinerung der Strukturparameter in der Raumgruppe P6 3 /m. Abstract.Single crystals of eight new compounds were prepared by heating mixtures of the elements in a lead flux. They were in… Show more

“…In some cases better crystal‐growth results have been obtained using a lead flux rather than tin, especially for compounds with the platinum metals, which form very stable stannides, as already pointed out above. Recent examples for products from such reactions are Ca 2 Ir 12 P 7 , Ca 5 T 19 P 12 ( T =Rh, Ir), or Eu 6 Rh 30 As 19 ,186 AE Ir 2 P 2 ( AE =Ca, Sr, Ba),187 Sr 2 Rh 7 P 6 ,188 and MgRh 6 P 4 189. The elements can be treated with an excess of lead at 1100 °C in an alumina crucible that is sealed in a silica ampoule.…”

“…In einigen Fällen wurden jedoch mit flüssigem Blei bessere Ergebnisse erzielt, insbesondere bei Verbindungen, die Platinmetalle enthalten, da diese sehr stabile Stannide bilden, wie schon oben erwähnt. So wurden kürzlich die Verbindungen Ca 2 Ir 12 P 7 , Ca 5 T 19 P 12 ( T =Rh, Ir) oder Eu 6 Rh 30 As 19 ,186 AE Ir 2 P 2 ( AE =Ca, Sr, Ba),187 Sr 2 Rh 7 P 6 188 und MgRh 6 P 4 189 durch Reaktionen in flüssigem Blei hergestellt. Die Elemente können dabei mit einem Überschuss an Blei bei 1100 °C in einem Korundtiegel, der seinerseits in eine Quarzglasampulle eingeschlossen ist, zur Reaktion gebracht werden.…”

“…Inorganic Chemistry ARTICLE polyanion of the La 4 Rh 8 P 9 structure contains isolated P 3phosphide anions besides the rarely observed species of doubly bonded P 2 2units. Herein, we report on the synthesis and structure determination of this new phosphide, its magnetic and bonding properties, and the differentiation of the crystallographically distinct phosphorus sites by 31 P solid state NMR spectroscopy.…”
