Thymine hydrogen peroxide 0.55‐solvate 0.45‐hydrate
TLDR
In this paper, a three-dimensional hydrogen-bonded network of peroxide and water molecules is proposed to give the title hydrogen peroxide water solvate, C5H6N2O2·0.45H2O.Abstract:
Thymine crystallizes from 50% hydrogen peroxide to give the title hydrogen peroxide water solvate, C5H6N2O2·0.55H2O2·0.45H2O. The disordered peroxide and water molecules occupy the same positions. Thymine molecules are linked together by N—H⋯O hydrogen bonds forming chains parallel to the ac diagonal. Hydrogen peroxide molecules are combined by O—H⋯O hydrogen bonds to give chains parallel to the c axis. Both kinds of chains are organized in a three-dimensional hydrogen-bonded network.read more
