Crystal structure and Hirshfeld surface analysis of 2-[(2-oxo-2H-chromen-4-yl)-oxy]acetic acid dimethyl sulfoxide monosolvate.

ABSTRACT: The title compound, C₁₁H₈O₅·(CH₃)₂SO, is a new coumarin derivative. The asymmetric unit contains two coumarin mol-ecules (A and B) and two di-methyl-sulfoxide solvent mol-ecules (A and B). The dihedral angle between the pyran and benzene rings in the chromene moiety is 3.56 (2)° for mol-ecule A and 1.83 (2)° for mol-ecule B. In mol-ecule A, the dimethyl sulfoxide sulfur atom is disordered over two positions with a refined occupancy ratio of 0.782 (5):0.218 (5). In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains running along the c-axis direction. The chains are linked by C-H⋯O hydrogen bonds, forming layers parallel to the ac plane. In addition, t
