Diammonium carbonate hydrogen peroxide monosolvate, 2NH(4)(+)·CO(3)(2-)·H(2)O(2), (I), and dicaesium carbonate hydrogen peroxide trisolvate, 2Cs(+)·CO(3)(2-)·3H(2)O(2), (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.

“…In the late 1970s Adams and coworker reported several peroxosolvates of guanidinium salts, namely oxalate dihydrate peroxosolvate [15,16], pyrophosphate sesquihydrate peroxosolvate [17], and pyromellitate trihydrate peroxosolvate [18]. All of them demonstrated high stability to the loss of solvated peroxide in open air due to durable 3D-hy-drogen bonded nets, but it was observed that pyromellitate salt «decomposes continuously with small explosions» [18].…”

Thymine molecules are linked together by N-HÁ Á ÁO hydrogen bonds forming chains parallel to the ac diagonal. Hydrogen peroxide molecules are combined by O-HÁ Á ÁO hydrogen bonds to give chains parallel to the c axis. Both kinds of chains are organized in a three-dimensional hydrogen-bonded network. 2 O M r = 152.93 Monoclinic, P2 1 =c a = 6.5047 (16) Å b = 19.194 (5) Å c = 5.6190 (13) Å = 110.078 (5) V = 658.9 (3) Å 3 Z = 4 Mo K radiation = 0.13 mm À1 T = 120 (2) K 0.20 Â 0.20 Â 0.10 mm Data collection Bruker SMART 1K diffractometer Absorption correction: multi-scan (SADABS; Bruker, 2003) T min = 0.974, T max = 0.987 4556 measured reflections 1733 independent reflections 1174 reflections with I > 2(I) R int = 0.038
