Coordination Number

Postby Genisis Cabral » Sun Dec 03, 2017 6:30 pm

To clarify, is the coordination number simply the number of bonds so if you were determining it based off of the lewis structure would you count the bonds the central atom has?

Hey!

So to clarify, the coordination number of a coordination compound refers to the number of points that the ligands (Lewis bases) are attached to the central metal atom. For example, the coordination number of Ni(CO)4, is 4 because the Lewis bases in CO are able to bind to Nickel four times.

hope this helps! :)

To find the coordination number, only look at the elements within the brackets and the number of ligands attached to the transition metal. Anything outside the brackets should not be counted.

Yes, it is the number of bonds attached to the central atom, but only referring to the ligands (ignore cations/anions).

how do you figure out the coordinate number of complex structures that are not obvious when you look at it?
