Oyonite belongs to the Sb-rich members of the andorite homeotypic sub-series. Chemically similar to menchettiite, lasmanisite, and uchucchacuaite. Also compare ramdohrite and 'dürfeldtite'.

Also compare luboržákite.

A phase chemically similar to oyonite, but with the (Pb-poorer) "approximate composition MnPbAg₂Sb₄As₂S₁₂" is reported by Kasatkin et al. (2022).
