title: Crystal structure of 6-hy-droxy-5-(2-meth-oxy-phenoxy)-2,2'-bipyrimidin-4(3H)-one.
abstract: In the title compound, C15H12N4O4, the dihedral angle between the heterocyclic rings is 12.60 (8)°, and that between the benzene ring and the adjacent heterocyclic ring is 85.14 (6)°. In the crystal, a combination of N-H⋯O and O-H⋯O hydrogen bonds link mol-ecules related by a glide plane into a C(5) C(6)[R (2) 2(9)] chain of rings, which is a distinctly different packing motif to those observed in hydrated modifications of this compound.
