PtO4 does not exist so no-one knows what the bonding is. PtO2 is known but a full structure determination of the anhydrous compound has not been made but it is believed to have a layer structure similar to that of CdI2 cadmium iodide. In this structure the metal atom is 6 coordinate. Simply termed as ionic it has covalent character.
