How come in coordination compounds the bonding ligand does not receive a charge reflecting its newly established bond? For example in cisplatin the amine groups are neutral in charge (however they have four bonds) but if the amine was bound to an organic molecule it would receive a formal charge of +1.
Furthermore, why would the oxygen in H2O ever want to coordinate? This seems particularly weird because oxygen typically does not "like" to freely give/share electrons with other atoms.
Sorry to ask what might seem as obvious questions, I am but an undergrad who has taken only 5 semesters worth of chemistry.
