Osmium compounds are compounds containing the element osmium (Os). Osmium forms compounds with oxidation states ranging from −2 to +8. The most common oxidation states are +2, +3, +4, and +8. The +8 oxidation state is notable for being the highest attained by any chemical element aside from iridium's +9[1] and is encountered only in xenon,[2][3] ruthenium,[4] hassium,[5] iridium,[6] and plutonium.[7][8] The oxidation states −1 and −2 represented by the two reactive compounds Na 2[Os 4(CO) 13] and Na 2[Os(CO) 4] are used in the synthesis of osmium cluster compounds.[9][10]
