| DRAFT DEFINITION |
| Onium Ions |
|---|
| Positively charged higher-valency (higher-coordination) ions of the nonmetallic elements. More common types are the carbonium, oxonium, sulfonium, nitronium, diazonium, phosphonium, and halonium ions. Classical examples are the methonium ion CH5+, the hydrogenonium ion H3+ and and the hydronium ion H3O+. Onium ions are not limited to monopositive ions, and multiply-charged onium ions exist such as H4O2+ and the distonic oxonium dication H2O+-CH2-CH2-OH2+. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
