The +2 oxidation state is common for nickel and palladium, while +2 and +4 are common for platinum. Oxidation states of -2 and -1 have also been observed for nickel [3] [4] and platinum, [5] and an oxidation state of +5 has been observed for palladium [6] and platinum. [7] Platinum has also been observed in oxidations states of -3 [8] and +6. [9]
