In the title compound, C(10)H(12)N(8)O(4)·H(2)O, prepared from the reaction of glycoluril with paraformaldehyde, the organic molecule has mm symmetry. The asymmetric unit comprises one quarter of the mol-ecule and a half-mol-ecule of water. The dimer is formed by bridging two glycoluril mol-ecules with methyl-ene groups at the 1 and 6 positions. In the crystal structure, mol-ecules are linked via N-H⋯O and O-H⋯O hydrogen bonds, forming a two-dimensional framework.
在由甘脲与多聚甲醛反应制备的标题化合物C₁₀H₁₂N₈O₄·H₂O中,有机分子具有mm对称性。不对称单元包含四分之一的分子和半个水分子。二聚体是通过在1和6位用亚甲基桥连两个甘脲分子形成的。在晶体结构中,分子通过N—H⋯O和O—H⋯O氢键相连,形成二维框架。
