title: 3-(4-Hy-droxy-phen-yl)-7-meth-oxy-chroman-4-one monohydrate.
abstract: In the title compound, C(16)H(14)O(4)·H(2)O, the dihedral angle betwen the benzene rings is 71.4 (6)°. The pyran ring is in a sofa conformation. In the crystal, O-H⋯O hydrogen bonds connect the components into a two-dimensional network parallel to (010), incorporating C(2) (2)(4) and C(2) (2)(11) chains. In addition, weak C-H⋯O, C-H⋯π and π-π stacking inter-actions [centroid-centroid distance = 3.768 (2) Å] are present.
