Crystal structure of N-methylanilinium 5,7-dihydroxy-4-oxo-2-phenyl-4H-chromene-8-sulfonate monohydrate, C22H21NO8S

“…The chrysin-8-sulfonate skeleton has an essentially planar conformation, with mean deviation from this plane of 0.0235(3) Å. The bond lengths and angles of anion and cation are similar to those found in literature [11,12]. In the crystal structure of title compound, hydrogen bonds connect chrysin-8-sulfonate into dimers, and the adjacent dimers are further connected by hydrogen bonds to form one-dimensional chain along the directions of [011], [010] and axis a, respectively.…”
