Ok so I understand how a ligand works and all that stuff, but I noticed in my text book it says when ammonia is replacing water ligands there is a different effect for cobalt than there is for copper.
For instance, When reacting with cobalt, the OH- ion first creates Cobalt hydroxide and this goes on to react with the ammonia to form Co(NH3)6 and 2 hydroxide ions, whereas for copper, the same thing happens to create a copper hydroxide ion, however this reacts with ammonia, but this time 2 other water ligands to from Cu(NH3)4(H2O)2^2+
Why is this different? Any help appreciated and good luck to everyone doing unit 5 and chemistry A level in general!

Basically 6 NH3 ligands cannot all fit onto the the central metal ion (copper) therefore only four H20 ligands are replaced giving the complex Cu(NH3)4(H2O)2^2+ , this is the only complex that this happens to that's been mentioned in the spec I believe
