Maximum number of ligands

Postby Justin Lau 1D » Wed Nov 15, 2017 4:27 pm

Are six ligands the maximum amount of ligands that can be attached to any cation for coordination compounds? Could this number possibly be exceeded if, say, there was a stronger cation charge or more d orbital electrons?

Six is the maximum number of ligands, at least as far as the textbook gets into. This is because the electron pairs repel each other and realistically can't form a bond angle that would be less than 90º

I guess it is, but we might not go that further into that.

I believe that the octahedral shape is the maximum number of ligands that can be added. If there are more it may be unstable.
