The aromatic rings of the title compound, C(13)H(10)O(3)·H(2)O, are aligned at dihedral angles of 20.6 (1) and 40.8 (1)° with respect to the triangular C(ar-yl)-C(=O)-C(ar-yl) fragment. The hy-droxy groups are each hydrogen-bond donors to separate water mol-ecules, the water mol-ecule itself being hydrogen-bonded to one hy-droxy group and one carbonyl group. The water mol-ecule exists in an unusual four-coordinate environment in the resulting layer structure.
标题化合物C(13)H(10)O(3)·H(2)O的芳环相对于三角形的C(芳基)-C(=O)-C(芳基)片段以20.6 (1)°和40.8 (1)°的二面角排列。每个羟基都是与不同水分子形成氢键的供体,水分子本身与一个羟基和一个羰基形成氢键。在所得的层状结构中,水分子存在于一种不寻常的四配位环境中。
