Abstract
In the title compound, C(27)H(30)O(14)·H(2)O, the hydroxy-phenyl ring makes a dihedral angle of 20.05 (11)° with the chromenone ring system. The crystal structure is stabilized by intra- and inter-molecular O-H⋯O hydrogen bonds. The absolute configuration was assigned on the basis of an analagous structure.
摘要
在标题化合物C(27)H(30)O(14)·H(2)O中，羟苯基环与色酮环系统形成的二面角为20.05 (11)°。晶体结构通过分子内和分子间的O—H⋯O氢键得以稳定。绝对构型是根据一个类似结构确定的。
