Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2−. Amide ligands have two electron pairs available for bonding. In principle, they can be terminal or bridging.

Electrons are found in predictable locations around an atom's nucleus, called orbitals. Most metals have a large number of accessible electrons compared to light main group elements such as nitrogen, oxygen, or carbon.

[Fe(CN) 6] 3-not [Fe(NC) 6] 3-(Note: this rule primarily is used for ambidentate ligands; although IUPAC reccomends that aqua ligands be written as OH 2 when the O would be closest to its coordinated metal they are still usually written as H 2 O). 2021-03-14 · Metal complexation with picrate salts gave crystalline products that could be structurally characterised for calcium, lanthanum, praseodymium, and ytterbium. While the details of these structures vary, the metal–ligand interactions are remarkably consistent, with coordination polymers formed through interaction between three of the amide O atoms, each binding to a different metal atom.
