| Abstract: | The diiodides NdI2 and DyI2 react with nitrogen at an atmospheric pressure at 2704-550 °C to give the nitrides (LnI2)3N (Ln = Nd and Dy). The products obtained are insoluble in organic solvents; in THF, they rapidly disproportionate into LnI3(THF)3 and the iodide nitrides (NdI)3N2 of unclear structures. The nitrides (NdI2)3N and (DyI2)3N can be completely hydrolyzed into ammonia, the triiodide hydrates LnI3(H2O)2, and the monoiodide hydrates LnI(OH)2(H2O). A reaction of (NdI2)3N with excess iodobenzene in THF gives Ph3N and PhNH2 in 9 and 5% yields, respectively. Reactions of (NdI2)3N with propyl chloride, benzyl chloride, and acetyl chloride produce no nitrogen-containing products. A reaction of (NdI2)3N with CpK gives Cp3Nd(THF) in 63% yield. |
