Abstract: The trans stereochemical relationship of the two substituents of the title compound, C₉H₁₂N₂O₅, a new spiro-nucleoside, has been confirmed. The cyclopentane moiety adopts the C3'-endo-type conformation, while the barbiturate ring is almost planar. Molecules interconnected by a two-dimensional network of hydrogen bonds build layers parallel to the ab plane.
