Ytterbium nitride

The changes in catalytic activities of rare earths introduced into zeolite with the evacuation temperature suggest that the Eu(II) and Yb(II) imide species formed exhibit activity for the isomerization and the Michael reaction (Baba et al. 1993, 1995). Unlike the results on R/C (Imamura et al. 1996a), the nitride species obtained by evacuating R/zeolite around 900 K are catalytically active for the hydrogenation of ethene. However, there is a difference in valence state between europium nitride and ytterbium nitride the former is divalent, while the latter is trivalent. 

A common precursor to LnN are the simple inorganic amides Ln(NH2)x (x = 2, 3) which can be placed between the nitrides and the alkyl substituted amides. Their main use lies in the synthesis of other solid materials like lanthanide hydroxides [21,33], carbides [34] or above-mentioned nitrides. Very recently solutions of europium and ytterbium in liquid ammonia have been rediscovered as synthetic tools (Sect. 7.1).
