Wikipedia

  1. Onium

    An onium (plural: onia) is a bound state of a particle and its antiparticle. These states are usually named by adding the suffix -onium to the name of one of the constituent particles (replacing an -on suffix when present), with one exception for "muonium"; a muon–antimuon bound pair is called "true muonium" to avoid confusion with old nomenclature.

However, despite its name, muonium is not a muon–antimuon onium because IUPAC assigned the name to the system of an antimuon bound with an electron.
