Synthese und Kristallstruktur von Gd₂ NCl₃ / Synthesis and Crystal Structure of Gd₂ NCl₃

Abstract

Abstract The new compound Gd 2 NCl 3 is formed from GdCl 3 with Gd and N 2 as well as from GdCl 3 with GdN (at 1020 K). The crystal structure contains NGd 4 tetrahedra, which are linked via opposite edges to form infinite chains (Orthorhombic, Pbcn; a = 1301.7(1), b = 673.10(6), c = 614.03(7) pm; R = 0.031 for 578 independent reflections). The formal analogy with structures containing condensed clusters, e.g. Gd 2 Cl 3 , is discussed.
