Ag2O3 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Ag3+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are a spread of Ag–O bond distances ranging from 2.00–2.09 Å. There are two inequivalent O2- sites.

银离子具有极强的杀菌活性，银参与杀菌活性作用也有不同价键表现形式，不同价银有不同的杀菌性能，它们的杀菌相对能力如下：Ag (III) ＞ Ag (II) ＞ Ag (I) ＞Ag。 三价银杀菌能力最强，分子结构中的两个三价银离子遇到微生物后，使微生物的 蛋白质变性 而导致其死亡。 三氧化二银，黑色固体，一定条件下，如遇水，极易分解为AgO（2010年经Jeremy P. Allen等人证实，其为混合物，正确构成应为Ag2O·Ag2O3），然后继续分解为Ag2O，最终产物应该为Ag，即银单质。

Silver oxide is the chemical compound with the formula Ag 2 O. It is a fine black or dark brown powder that is used to prepare other silver compounds.

Crystalline silver (III) oxide, which is stable over prolonged periods at −20°C, was obtained by anodic oxidation of AgClO 4, AgBF 4 or AgPF 6 (not AgNO 3) in aqueous solution. The oxide of definite composition Ag 2 O 3 was hitherto unknown. It arouses interest as a possible component of the anodes in zinc/silver oxide primary cells.

Silver (I,III) oxide or tetrasilver tetroxide is the inorganic compound with the formula Ag 4 O 4. It is a component of silver zinc batteries. It can be prepared by the slow addition of a silver (I) salt to a persulfate solution e.g. AgNO 3 to a Na 2 S 2 O 8 solution. [1] . It adopts an unusual structure, being a mixed-valence compound. [2] .

《民声面对面》北京讯（毛伟） 三价银离子（氧化高银）——尽管AgO中银的平均氧化态为+2，其与CuO为同晶型:602，但理论计算表明氧化银 (I,III)比氧化银 (II)稳定，这可能与银的第二电离能比铜大有关。 另外， 对AgO粉末的XRD检测结果表明其为反磁性:602,说明Ag的价态不可能是+2有可能是+1和+3的混合价态。 中子衍射 结果也表明它的结构式应为AgIAgIIIO2:1181或者 Ag O·Ag O。

Reduction curves show a minimum in the potential decay of the higher oxide preceding the formation of Ag?O. The "Ag.'03" decomposes in approximately 1 h at -40 'C to either Ago or Ag20. 'I'he activation energy for its thermal decomposition is 12.0 + 2.0 kcal/mole.
