摘要：

In the two independent but very similar molecules (A and B) of the title compound, C(14)H(16)N(2)O(8), both six-membered pyrimidine rings are nearly planar [maximum deviations = 0.010 (3) angstrom in A and 0.028 (3) angstrom in B]. The five-membered furanose ring in molecule A adopts an envelope conformation, while the same ring in molecule B has a twisted conformation. In the crystal, the A molecules are linked via a pair of intermolecular N-H center dot center dot center dot O hydrogen bonds, forming dimers. Each A molecule is further linked to a B molecule via a second N-H center dot center dot center dot O hydrogen bond. There are also a number of C-H center dot center dot center dot O interactions present, leading to the formation of a three-dimensional network.
