摘要
Diammonium carbonate hydrogen peroxide monosolvate, 2NH4+center dot CO32-center dot H2O2, (I), and dicaesium carbonate hydrogen peroxide trisolvate, 2Cs+center dot CO32-center dot 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.
