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.

Experimental stability constant data, kinetic information, spectroscopic (IR, NMR, ESR, and electronic) measurements, circular dichroism spectroscopy and some data from X-ray crystal structures were used to examine amide metal interactions in these polydentate ligands. The coordination of metal ions to the free acrylamide or to the amide residue of an acrylamide adduct may play a catalytic role in prompting biochemical reactions, that either the vinylic group or the amide residue can undergo. It is clear that metal atoms coordinated to an organic substrate affect the reactivity of the substrate. Written by internationally recognised leaders in the field, Metal Amide Chemistry is the authoritative survey of this important class of compounds, the first since Lappert and Power’s 1980 book “Metal and Metalloid Amides.” An introduction to the topic is followed by in-depth discussions of the amide compounds of: alkali metals alkaline earth metals zinc, cadmium and mercury the The dark green Fe[N(SiMe 3) 2] 2 complex exists in two forms depending on its physical state. At room temperature the compound is a monomeric liquid with two-coordinate Fe centers possessing S 4 symmetry, in the solid state it forms a dimer with trigonal planar iron centers and bridging amido groups. MOF-like materials by metal coordination between carboxyl groups,19 the design of such structures is problematic as the nitrogen of the amide moiety is a good Lewis base and thus it can also coordinate to the metal, leading to loss of structure.20 In case of transition metals, in particular Ni(II) and Cu(II), Donor and ate‐Coordination in Rare‐Earth Metal Bis(dimethylsilyl)amide Complexes † Christian Meermann Department of Chemistry, University of Bergen, Allégaten 41, 5007 Bergen, Norway, Fax: +47‐55589490 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.

oxygen donors. One must note that the amide nitrogen is completely non-basic and does not coordinate to metal ions unless it is deprotonated (Figure 2). Coordination occurs through the carbonyl oxygen of the amide group.
In contrast, Ca2+ and Mg2+ were coordinated by the amide group of 1 in both the keto and enol forms.

Amide bond cleavage initiated by coordination essential for a metal centre to bind to the amide bond and the metal centre is of suﬃcient Lewis acidity.
In principle, they can be terminal or bridging. In these two examples, the dimethylamido ligands are both bridging and terminal:
The structures of complexes between amides and metal ions were examined by FAB mass spectrometry and collision-induced dissociation (CID).
