### coordination number

I m still a little confused on how to get a coordination number is it the number of bonds? because the example he gave in the lecture was [Fe(CN)6]^14- and the coordination number was 6?

Hi! You are correct! Dr. Lavelle mentioned that the coordination number is the number of bonds.

### Re: coordination number

The coordination number is the number of bonds. So, if there is a double bond in a coordination compound, that would count as a coordination number of 2.

### Re: coordination number

It would be six because the coordinate number is proportional to the number of bonds. also note, if there is a double or a triple bond, you count those as 2 or 3 respectively.

### Re: coordination number

The coordination number is the number of bonds present within the molecule. In [Fe(CN)6]^4-, the coordination number is 6 since there are 6 things bonded to the central atom.

### Re: coordination number

I reflect everything everyone has said above, but also be wary the coordination number is for every bond that attaches to the central atom (make sure you don't ever count the bonds between say the C and N.

### Re: coordination number

Yes, the coordination number is the number on bonds from the central atom. Double bonds count as two and triple bonds count as three.

### Re: coordination number

The [Fe(CN)6]-4 has a coordination number of 6 because it is octahedral shape with the Fe at the center meaning it has 6 bonds connecting to the central atom

### Re: coordination number

yes! this is because coordination number, unlike hybridization number pertains to the number of bonds! since there are six bonds, the coordination number would be 6!

### Re: coordination number

Yes, it is equal to the total number of bonds. A single bond gives one, double bond gives two, and a triple bond gives 3.

Oh, that turned out to be simpler than I thought
