On Seleno- and Telluroarsenites, -antimonites, and -bismutitesThe new compounds NaAsSe2, NaSbSe2, NaSbTe2, and NaBiTe2 have been prepared and their structures determined. NaSbSe2, NaSbTe2, and NaBiTe2 build up the NaCl structure with the following lattice constants: NaSbSe2: a = 596.6(2) pm, NaSbTe2: a = 631.7(2) pm, NaBiTe2: a = 636.6(3) pm. NaAsSe2 crystallizes orthorhombic with a = 583 ± 1pm, b = 2427 ± 5 pm, c = 1182 ± 2 pm, Pbca. In the structure there are distorted trigonal AsSe3 pyramids which are connected by corners to chains.
Notes:
Die neuen Verbindungen NaAsSe2, NaSbSe2, NaSbTe2 und NaBiTe2 wurden dargestellt und strukturell aufgeklärt. NaSbSe2, NaSbTe2 und NaBiTe2 kristallisieren in der NaCl-Struktur mit folgenden Gitterkonstanten: NaSbSe2: a = 596,6(2) pm, NaSbTe2: a = 631,7(2) pm, NaBiTe2: a = 636,6(3) pm. NaAsSe2 kristallisiert orthorhombisch mit a = 583 ± 1 pm, b = 2427 ± 5 pm, c = 1182 ± 2 pm, Pbca. In der Struktur liegen Ketten aus eckenverknüpften trigonalen AsSe3-Pyramiden vor.
