Is NO3- an ambidentate ligand?
To determine whether NO3- (nitrate ion) is an ambidentate ligand, we need to understand what an ambidentate ligand is.
An ambidentate ligand is a ligand that can bind to a metal ion through different atoms or different coordination sites. It can form a coordinate bond by donating either one atom or another atom within the ligand.
In the case of NO3-, it is a polyatomic ion consisting of one nitrogen atom bonded to three oxygen atoms (N-O bonds). According to its structure and electron distribution, NO3- cannot form coordination bonds by donating through different atoms within the same molecule. Hence, it is not considered an ambidentate ligand.
However, it is worth noting that NO3- can coordinate to metals as a whole ion, providing it with multiple coordination sites. In this case, it is acting as a monodentate ligand by donating through one coordination site.
I don't think so but it is a new term to me. http://www.chemicool.com/definition/ambidentate.html
NO3^- only bonds through the N atom and not through the O atoms.
