1,3,5,7,9,11,13,15-Octa­azapenta­cyclo­[9.5.1.13,9.06,18.014,17]octa­decane-4,8,12,16-tetrone monohydrate: a methyl­ene-bridged glycoluril dimer

摘要

In the title compound, C10H12N8O4·H2O, prepared from the reaction of glycoluril with paraformaldehyde, the organic molecule has mm symmetry. The asymmetric unit comprises one quarter of the mol­ecule and a half-mol­ecule of water. The dimer is formed by bridging two glycoluril mol­ecules with methyl­ene groups at the 1 and 6 positions. In the crystal structure, mol­ecules are linked via N—H⋯O and O—H⋯O hydrogen bonds, forming a two-dimensional framework.
