Ligand Definition
How exactly would you define a ligand, and what constitutes one? Are ligands always made of polyatomic ions? Or is that just a possibility

Re: Ligand Definition
In this class, ligands are molecules that donate a lone pair of electrons to a transition metal through a coordinate covalent bond. Also ligands don't always have to be polyatomic ions, but they are frequently polyatomic ions.
Re: Ligand Definition
I like to simplify it and just remember a ligand as an atom or polyatomic ion attached to the central metal atom by coordinate covalent bonds.

Re: Ligand Definition
A ligand is just a molecule or ion that binds via coordinate covalent bonds to a central metal species. Ligands do not always have to be polyatomic ions as they just need to be able to have a coordinate covalent bond with the central metal species, an example would be Br- which is seen on the week 9 problem 6 achieve homework.

Re: Ligand Definition
Molecules that donate a lone pair of electrons to a transition metal via coordinate covalent bond are also known as ligands and are thus usually polyatomic ions.

Re: Ligand Definition
A ligand is an atom or ion that is bonded to the central atom, it is also an electron donor so it has at least one lone pair.

Re: Ligand Definition
A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex, hope that helps

Do coordinate covalent bonds only happen in the bonding of metal ions to ligand?

Re: Ligand Definition
Ligands are an ion or molecule that is attached to a metal atom by coordinate bonding, and gives off a pair of electrons to the central metal ion

Re: Ligand Definition
Ligands are defined as the electron donating species directly attached to the central ion to make up the coordination sphere.

Re: Ligand Definition
Ligands are atoms or molecules that bond to a central metal ion atom through a coordinate bond. A coordinate bond is produced as the ligand shares 2 of its electrons to the metal ion instead of ligand sharing one and the metal sharing 1. A ligand does not have to be polyatomic, but it commonly is.

Re: Ligand Definition
A ligand is a ion or molecule that donates electrons through a coordinate covalent bond to a central metal cation.
Re: Ligand Definition
A ligand is a neutral molecule or charged ion that acts as lewis base by donating a lone pair of electrons that can be used to form a bond to a metal ion. Yes, polyatomic ions could be ligands because they fit this definition.

Re: Ligand Definition
Hi!
For this class, you should define ligand as an atom or poly atomic ion, which it doesn’t have to be but often is, which donates a pair of electrons to a transition metal through a coordinate covalent bond.
Hope this helps!

Hi Aida!
I believe a ligand can form a coordinate compound only with a transition metal because of the possibility of an expanded octet.
Hope this helps!
