Abstract:
In the title compound, C10H8O3 (systematic name 3-hy-droxy-methyl-4H-chromen-4-one), the fused-ring system is slightly puckered [dihedral angle between the rings = 3.84 (11)°]. The hy-droxy O atom deviates from the heterocyclic ring by 1.422 (1) Å. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(12) loops. The dimers are linked by aromatic π-π stacking [shortest centroid-centroid distance = 3.580 (3) Å], and C-H⋯O hydrogen bonds, generating a three-dimensional network.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
