Summary 5-Carboxymethylaminomethyluridine crystallizes as a zwitterion in the monoclinic space group P21 witha=5.414 (2) Å,b=16.626 (2) Å,c=8.322 (1) Å, β=96.86 (a) Å,V=745.2 (3) Å3,Z=2,D=1.56 g/cm3. The structure was solved by direct methods and refined toR=0.061. The ribose ring assumes a C3′-endo-C2′-exo conformation and the torsion angle ϕCN is 9.6 (5)°. In the crystal, there are two intra- and ten intermolecular hydrogen bonds per asymmetrical unit.
