Crystal structure of 6-hydroxy-5-(2-methoxyphenoxy)-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 molecules related by a glide plane into a C(5) C(6)[R22(9)] chain of rings, which is a distinctly different packing motif to those observed in hydrated modifications of this compound.
