WebIn order to balance the charge of 2 chloride ions (-1 each), we need a +2 charge, so this is the charge of the complex. The type of ligand in this case is just water, a neutral molecule (i.e. its charge = 0). Therefore, if the whole complex has a charge +2 and the ligand has charge 0, it means that the +2 charge comes from the metal: Fe 2+.
