Crystal structure and Hirshfeld surface analysis of luteolin dimethyl sulfoxide monosolvate

Abstract

The title compound crystallizes in the monoclinic space group P2₁. The luteolin mol­ecule adopts a planar conformation, and the crystal structure is consolidated by extensive hydrogen-bonding inter­actions.

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.
