Ligands

[Lusin_Yengibaryan_3B]

How do we determine the number of ligands in a compound and then use that to determine the coordination compound of the structure?

[BrittneyMyint1D]

Since ligands are Lewis bases (electron pair donors), I believe you would try identifying which molecule is donating an electron pair to form a coordinate covalent bond. From there, you could possibly determine the number of ligands. As a result of coordinate covalent bond formation, a coordination compound is made. Hope this answers your question!

The number of ligands attached to central ion, which is actually the number of donor atoms is basically the coordination number.

[Nicolette Simoni 3L]

The number of ligands attached to central ion, which is actually the number of donor atoms is basically the coordination number.

In other words, the number of bonds also equals the coordination sphere! For example, with [Fe(CN)6]4- everything within the bracket is inside the coordination sphere, and with that knowledge you know that the coordination number is 6! This example was taken from Lecture #24 if you're still confused I recommend reaching it :). Hope this helps!

The number of ligands would correspond to the number of atoms (Lewis base) that are attached to the cation (central atom). So the number of bonds that molecule has.

[Shrinidhy Srinivas 3L]

You can identify the number of ligands by thinking about the coordination sphere and the coordination number of the compound (which is the amount of bonds to the central atom). Hope this helps!

[Gustavo_Chavez_1K]

So the ligands are essentially the atoms that are attached to rhe central atom. We can calculate the coordination number by looking at the number of ligands (or atoms) that are attached to the central atom.

[Anthony_Sandoval_1D]

Ligands are atoms which are attached to the central atom or cation. Coordination number is calculated by counting the number of ligands attached the central atom.

[Michael Cardenas 3B]

The number of ligands is the number of atoms attached to the central atom and the coordination number can be found by simply finding the number of ligands.

[Mina Tadros 3L]

The number of ligands is the number of lewis bases (electron-pair donors) attached to the central metal cation. This would also be the coordination number for the coordination compound.
