Let's say in your example:
porphyrine total charge = -2; Zn total charge = +2
Total charge of your whole system = 0
- In this example, if you split your system into 2 parts:
porphyrine total charge obvisouly = -2
Zn total charge obvisouly = +2
I think this is not realistic: The ligands of Zn should affect its
charge value...
- Now if you do not split your system into 2 parts, the charge of Zn
should be quite different from +2
