Coordination Number

[Daniel N]

How would I go about assigning a coordination number to a coordination compound?

The coordination number is equal to the number of coordinate covalent bonds. So when you are given a coordination compound, you can easily determine its coordination number by counting the number of ligands present keeping in mind that monodentate ligands form 1 coordinate covalent bond and that polydentate ligands form more bonds.

To find the coordination number from a compound, count how many bonds or ligands are attached to the metal atom. That should give you its coordination number.

[Elaine Steinberg 3H]

The coordination number is the number of bonds the central transition metal forms with ligands (molecules or charged ions that donate both pair/pairs of e- to form the bond). Sometimes these ligands can donate 2 lone pairs, as in the case of en (ethylenediamine). If you're given the formula for the compound, consider the species inside the brackets as forming the coordination compound.

To find the coordination number of an atom, you simply count the amount of bonds that are attached to the central metal atom.

[N Kanuri 2E]

The coordination number for a coordination compound is equal to the number of atoms attached to the central atom.

[Skylar Lo 2C]

The coordination number is the number of coordinate covalent bonds so just count the number of bonds it forms.

[Jane Wang 1E]

Coordination number is the total number of dative covalent bonds formed from the ligands to the central metal ion.

[Brandon Yu]

The coordination number is the number of ligands that are bound to the central atom.

[Cadence Chang]

Hi there!

As stated before, the coordination number refers to the number of bound atoms to the central atom.
Here are a few examples taken from the Achieve HW:

[M(CO)4Br2]
There are 4 CO molecules + 2 Br atoms attached to the central M atom. Therefore, the coordination number is 4 + 2 = 6.

[Cd(en)Br2]
In this case, en is bidentate, meaning that there are two binding sites. There are 2 binding atoms for en + 2 Br atoms attached to the central Cd atom. Therefore, the coordination number is 2 + 2 = 4.

Hope this helps! :)

the coordination number is the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.

[Nicole 3G]

Hello.

The coordination number is found by counting the number of bonded atoms to the central atom!

[505734174]

hello! to assign a coordination number, just count the number of ligands that are bonded to the central transition metal and the number of bonds is the coordination number.

[Lindsey Walter 3E]

The coordination number is the number of atoms attached to the central atom.

[Trisha Badjatia 2L]

The coordination number is the number of atoms bonded, or the number of sigma bonds between central atoms and ligands.

[Vivian Kim 3F]

Also just to add, there are some ligands such as (en) in it that are attached to the central atom more than once, so keep this in mind when finding the coordination number.

[Omeed Kalan]

Just count the number of bonds attached to the central atom

[Lizzy Bulla 3K]

The coordination number is equal to the number of ligand connected to the central atom

[Harshitha_Pandian_3F]

Coordinate Number is equal to the number of bonds that the metal ion has with its ligands. If there is a bidentate bond you would count that as two different bonds and the same for tri, and hexadentate.
