Platinum(II) forms many complexes, amond them those with the following ligands. Give the formula and charge of the complex with two ammonia molecules and one oxolate ion(C2O4^2-). Write the ligands in the order named. I somehow came to the conclusion that the charge is 0. However, I have no idea what a ligand is or how to write the answer to this question lol. Can someone please help?
