Physical properties
Because of the extreme cost and difficulty of producing hassium, hassium tetroxide has never been obtained in macroscopic amounts, as only a few molecules have ever been synthesized. As a result, many of its physical properties are experimentally uncharacterized and unknown. However, most research available generally shows hassium tetroxide to behave like a typical congener to osmium tetroxide. Hassium tetroxide is less volatile than osmium tetroxide.[2][3][4]
Synthesis
Hassium tetroxide can be obtained by reacting atomic hassium with oxygen at 600 °C.[3][2]
- Hs + 2 O2 → HsO4
Reactions
Hassium tetroxide can be combined with sodium hydroxide in an acid-base reaction, in which case it acts like the acid, to form sodium hassate(VIII):[5]
- HsO4 + 2 NaOH → Na2[HsO4(OH)2]
