N-Unsubstituted Amides - Derivatives of Ammonia

From the viewpoint of molecular chemists, inorganic metal amides or primary amides, the derivatives of ammonia, are related to solid state chemistry. However, both inorganic and organometallic amides are mentioned in the same breath. In a world of new materials where, e.g., ceramics [16,17] and hard 

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).
