Ten coordination polymers constructed from divalent metal salts, polycarboxylic acids, and bis-pyridyl-bis-amide ligands with different donor atom positions and flexibility are reported. They were structurally characterized by single-crystal X-ray diffraction. The ten coordination polymers are as follows: (1) {[Ni(L1)(3,5-PDA)(H2O)3]·2H2O}n (L1 = N,N′-di(3-pyridyl)suberoamide, 3,5-H2PDA = 3

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 Amidine, as ligand, have fascinating coordination modes, and their transition metal complexes also have been found to be a useful class of species with important applications. OSTI.GOV Journal Article: Coordination compounds of a number of d and f metals with amide ligands As the metal coordination should be orthogonal to the amide functional group, we selected a combination of azophilic metals and nitrogen-based bidentate coordination sites. Fig. 2a shows the generic structure of amide 1 with a 3-substituted-2-hydrazonopyridine moiety, which contains an amide (N Am ) and an adjacent imine (hydrazone of benzophenone; N Im ) functional group. In coordination chemistry, metal ammine complexes are metal complexes containing at least one ammonia ligand. "Ammine" is spelled this way due to historical reasons; in contrast, alkyl or aryl bearing ligands are spelt with a single "m". Almost all metal ions bind ammonia as a ligand, but the most prevalent examples of ammine complexes are for Cr, Co, Ni, Cu as well as several platinum group metals.

The structures of complexes between amides and metal ions were examined by FAB mass spectrometry and collision-induced dissociation (CID). Zn2+ was coordinated by the amide carbonyl oxygen atom of N-tetradecylacetamide (1). In contrast, Ca2+ and Mg2+ were coordinated by the amide group of 1 in both the keto and enol forms.

chromium is more mobile than surface chromium ions coordinated to oxide ions,. 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−.

Merely immobilising a successful metal complex catalyst to a functionalised support rarely yielded other than 6957 Rhodium Amide and Imidazole Complexes.

In principle, they can be terminal or bridging.

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. A literature review of structures of amide complexes of metal ions was carried out

Six-coordinate polymeric complexes involving coordination as a [NO] 2 -bis-bidentate through pyridyl-N and amide-O atoms were obtained with bivalent copper, nickel, cobalt and zinc. 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. 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.”.

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. In these two examples, the dimethylamido ligands are both bridging and terminal:
