The structure of 7,8-dihydroxy-4-methylcoumarin was determined by an X-ray diffraction method. The compound crystallized in the triclinic space group P1, Z=2, with a=7.631(2), b=9.456(5), c=7.075(3)Å, α=103.13(3), β=91.84(3), γ=68.21(3)°, and V=460.9(3)Å3. The X-ray crystal structure was also compared with those of 5,7-dihydroxy-4-methylcoumarin and 7-hydroxy-4-methylcoumarin.
