Abstract: Potassium(I) with 5,7-dihydroxy-6,4'-dimethoxyisoflavone-3'-sulfonate (L) assembles to K( $H_2O$ )L (L = 5,7-dihydroxy-6,4'-dimethoxyisoflavone-3'-sulfonate). It was characterized by single-crystal X-ray diffraction, element analysis, IR and $^1H$ NMR spectroscopy. It crystallizes in the monoclinic space group $P2_1$ /n and reveals a seven-coordinate complex. Polyhedra potassium chains, C-H ${\cdot}{\cdot}{\cdot}\pi$ and C-H ${\cdot}{\cdot}{\cdot}$ O and O-H ${\cdot}{\cdot}{\cdot}$ O hydrogen bonds lead K( $H_2O$ )L to a three-dimensional network structure. The biological activity of resistance to hypoxia was tested, and the results showed that the biological activity of resistance to hypoxia of K( $H_2O$ )L is as good as that of its precursor, irisolidone.
