Oxatriquinacene
It is an oxonium ion, with a tricoordinated oxygen atom with +1 charge connected to carbons 1,4, and 7 of a cyclononatriene ring, forming three fused pentagonal Oxatriquinacene has remarkable stability compared to other oxonium cations, although not as extreme as that of the similar oxatriquinane.

水合氢离子
水合氢离子(英语:Hydronium),也称离子、或氧𬭩(英语:Oxonium),指的是氢正离子与水分子配位结合而生成的正离子。与水结合之氢正离子,通常的来源为可溶于水的酸,可溶于水的酸溶在水中会解离成为酸根离子与氢离子,由于水分子能提供孤对电子,所以氢离子便与水分子配位结合而生成水合氢离子。

Hexafluorotitanic acid
According to X-ray crystallography, the salt consists of [TiF6]2- octahedral and two kinds of oxonium cations, (H3O)+ and (H5O2)+. As with most oxonium salts, it is only stable in acidic solution.

Polyoxetane
The propagation centre is a tertiary oxonium ion, mainly initialized by Lewis acids, trialkyl oxonium salts, carbocationic salts and others. Strong acids tend to generate secondary oxonium ions, which are unreactive, thus they are not initiators of first choice.
