- Binary Polyazides of Cerium and Gadolinium
-
Herein, we report on the preparation and full characterization (melting point, ATR-IR/Raman, elemental analysis, 14N NMR) of binary gadolinium(III) azide as DMSO solvate Gd(N3)3·8/3DMSO (DMSO = dimethylsulfoxide), along with the partially hydroxide substituted species Gd4(OH)2(N3)10·nDMSO (n = 8, 10). Moreover, the isolation and comprehensive characterization of hexaazido lanthanate(III) anions [Ln(N3)6]3– (Ln = Ce, Gd) in a series of [Ph4P]+ and [EtPh3P]+ salts is presented. Single-crystal structures of all compounds were determined, and the magnetic susceptibility in solution (NMR, Evans Method), as well as in the solid state (VSM), was investigated.
