Coordination compound - Coordination compound - Aqua complexes: Few ligands equal water with respect to the number and variety of metal ions with which they form complexes. Nearly all metallic elements form aqua complexes, frequently in more than one oxidation state. Such aqua complexes include hydrated ions in aqueous solution as well as hydrated salts such as hexaaquachromium(3+) chloride

Acrylamide is a weakly acidic and basic conjugated amide capable of coordinating to metal ions. 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. Inspired by natural bioinorganic systems that feature precisely positioned hydrogen-bond donors in the secondary coordination sphere to direct chemical transformations occurring at redox-active metal centers, we now report the design, synthesis, and characterization of a series of iron tetraphenylporphyrin (Fe-TPP) derivatives bearing amide "This book is a very timely summary of the metal amide chemistry that has surfaced over the past three decades .An indisputable success: I can recommend this book to all colleagues and students who are actively pursuing research in the fields of coordination, organic, and inorganic chemistry." Monomeric Group 13 Metal(I) Amides: Enforcing One-Coordination Through Extreme Ligand Steric Bulk By Deepak Dange (1726798), Jiaye Li (1464079), Christian Schenk (2003767), Hansgeorg Schnöckel (1655110) and Cameron Jones (1563892) Mechanically Twisting Amides inside a Self-Assembled Coordination Cage Enhance Their Reactivity (A) Structures of metal-coordination cages and amide guests and the results of hydrolysis. (B) X-ray single-crystal structures of the host-guest complexes of these different amides. Coordination of 2 a to the metal center causes a dissociation of the diphenylmethoxy moiety in 5 aa, thereby forming 7 aa, which undergoes an amine exchange reaction with HN(SiHMe 2) 2 to afford the double‐hydrosilylated product HN[Si(OCHPh 2)Me 2] 2 along with 8 aa. If the amide nitrogen deprotonated to form a coordination bond with the metal, the deprotonation of the α-amine would still be expected to show up on the titration curve. From the titration without the metal, the pKa of this proton is 7.46.
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.
Because the stability of a metal complex increases as the basicity of the ligands increases, we need to determine the relative basicity of the four ligands. When a ligand is bound to a metal through a particular atom, preferably place that atom closest the metal - e.g.
The structural formula is: - 2 - FOSCAVIR has the potential to chelate divalent metal ions, - such as calcium and magnesium, to form stable - coordination .
