Can someone help me understand just what a ligand is?
Is it used when referring to the bonds, or the whole substance?
if its referring to the bond, how is it any different than any other bond?
basically i'm just asking you to tell me all you know about ligands hahaha,
thank you in advance

Re: Some clarification about ligands
Basically a ligand is a Lewis base(which donates electrons) that attaches to the central metal atom. Ex:[Fe(CN)6]^-4. [CN] is a ligand that bings to iron. And the coordination number(number of points ligands attach) is 6. Hope other people can add more.

Re: Some clarification about ligands
Ligand refers to the atom or molecule that binds to the central metal atom. When Ammonia forms part of a coordination compound with a transition metal, such as Iron, Ammonia is considered a ligand.

Re: Some clarification about ligands
Ligand is another name for a Lewis base which bonds to a central metal atom/ion. A Lewis base is able to do this by the presence of lone pairs, allowing the atom to "donate" its electrons and covalently bond to the central metal atom.
This bond is called a coordination covalent bond, and the whole structure with connected ligands forms a coordinate complex. A coordinate compound is a electrically neutral compound that contains at least one complex. The coordinate number is the number of ligands connected to the central atom. E.g. Ni(CO) would have a coordination number of 4, as 4 ligands are connected to the central atom.

Re: Some clarification about ligands
A ligand is a Lewis base that bonds to a transition metal central atom. It doesn't refer to the entire compound.
