Coordination shape

Postby christabellej 1F » Mon Nov 25, 2019 9:09 am

In class, it was mentioned how a coordination number of 4 could mean that the molecule is either tetrahedral or square planar complex. How can you determine when a coordination sphere is a tetrahedral complex or square planar complex?

Lavelle did not go into too much depth about this but I believe that you have to draw the Lewis structure. If the molecule has a tetrahedral shape, it is a tetrahedral complex. If the molecule has a square planar shape, it is a square planar complex.

I believe you would need more information to identify exactly which shape it is such as hybridization or specific numbers of lone pairs/bonding pairs

Yeah. You can't know which one it is based on the coordination number alone. You would have to be given other information.
