Crystal structure and Hirshfeld surface analysis of luteolin dimethyl sulfoxide monosolvate

The title compound, 3′,4′,5,7-tetrahydroxyflavone dimethyl sulfoxide monosolvate (LUT-DMSO), C2H6OS·C15H10O6, crystallizes in the monoclinic space group P21. The LUT mol­ecule adopts a planar conformation, and the crystal structure is consolidated by extensive hydrogen-bonding inter­actions. Hirshfeld surface analysis indicates that the predominant inter­molecular inter­actions are O⋯H/H⋯O, C⋯H/H⋯C, and H⋯H, with these contacts contributing significantly to the overall cohesion of the crystal.
