Abstract

The central ring of the anthrone system in 1,8-diiodo-10-hydroxy-10-(3-methylbut-3-en-1-ynyl)anthrac en-9(10H)-one, C19H12I2O2, has a boat conformation and the two outer rings form a dihedral angle of 41.1 (2) degrees. The I-C bond lengths are 2.094 (4) and 2.083 (4) A. The hydroxyl and carbonyl groups form an intermolecular hydrogen bond having an O...O distance of 2.853 (4) A.
