Solution Summary
This solution is provided in 217 words. It references octahedral coordination in order to answer why square planar coordination occurs in certain ions.
Solution Preview
The d orbitals of metal split into two groups with octahedral coordination, like the following
- - dx2-y2, dz2
- - - dxy, dxz, dyz
When there are 7 d electrons, 6 go to the lower set of orbitals, one goes to the higher set of orbitals.
If we get ...
