Diammonium carbonate hydrogen peroxide monosolvate, 2NH4+·CO32-·H2O2, (I), and dicaesium carbonate hydrogen peroxide tris­olvate, 2Cs+·CO32-·3H2O2, (II), were crystallized from 98% hydrogen peroxide. In (I), the carbonate anions and peroxide solvent mol­ecules are arranged on twofold axes. The peroxide mol­ecules act as donors in only two hydrogen bonds with carbonate groups, forming chains along the a and c axes. In the structure of (II), there are three independent Cs+ ions, two of them residing on twofold axes, as are two of the four peroxide mol­ecules, one of which is disordered. Both structures comprise complicated three-dimensional hydro­gen-bonded networks.
