[Na(H2O)2(C18H15O6SO3)]2 was synthesized by sulfated 5-hydroxy-6,7,4′-trimethoxyisoflavone with concentrated sulfuric acid. Single-crystal X-ray diffraction study indicates that it is a dimeric centrosymmetric species. The coordination polyhedron of each Na(I) atom exhibits a distorted trigonal bipyramidal geometry. The dimeric units are linked by intermolecular hydrogen bonds C–H⋯π, C–H⋯O and O–H⋯O to result in a three-dimensional framework.

[Na(H2O)2(C18H15O6SO3)]2 是用浓硫酸硫酸化 5-羟基-6,7,4′-三甲氧基异黄酮合成的。单晶 X 射线衍射研究表明,它是一种二聚中心对称物种。每个 Na(I)原子的配位多面体呈现扭曲的三叉双锥几何形状。二聚单元通过分子间氢键 C-H⋯π、C-H⋯O 和 O-H⋯O 相连,形成一个三维框架。[Na(H2O)2(C18H15O6SO3)]2 是用浓硫酸硫酸化 5-羟基-6,7,4′-三甲氧基异黄酮合成的。每个 Na(I)原子的配位多面体呈现扭曲的三叉双锥几何形状。二聚中心对称单元通过分子间氢键 C-H⋯π、C-H⋯O 和 O-H⋯O 相连,形成一个三维框架。
