The crystal structure of 2,3H-2-methyl-4-(4-nitrophenyl)-5-oxobenzopyrano[3,4-e]dihydropyran-2-ol is investigated using X-ray diffraction. The unit cell contains an ethanol molecule that forms hydrogen bonds with O-H and C-O groups of two molecules of the main compound and acts as a proton donor and a proton acceptor in these hydrogen bonds. Owing to these interactions, infinite chains are formed in the crystal. The crystallographic data for the structure of C{sub 19}H{sub 15}NO{sub 6}.C{sub 2}H{sub 5}OH (M = 399.39) are as follows: the crystals are triclinic, space group P1, a = 5.5340(3) A, b = 8.0109(4) A, c = 11.0112(5) A, {alpha} = 88.773(2) deg., {beta} = 84.788(2) deg., {gamma} = 79.958(2) deg., and Z = 1.
