Commercially available 2-methyl-8-hydroxyquinoline was recrystallized from diethyl ether.
Carbon- and oxygen-bound H atoms were placed in calculated positions [C—H 0.93–0.96 Å and Uiso(H) = 1.2–1.5Ueq(C)], and were included in the
in the riding-model approximation. The hydroxyl H-atoms were located in a difference Fourier map, and were refined with a O—H distance restraint of 0.85 (1) Å.The
of the title compound contains two molecules; the corresponding bond lengths and angles of these two molecules agree with each other. In the solid state, the two independent molecules exist as O—H···N hydrogen-bonded dimer; the mean planes through the non-hydrogen atoms of the two molecules form a dihedral angle of 77.98 (5)°.Aluminium derivatives of 2-methyl-8-hydroxyquinoline are light-emitting compounds.

The asymmetric unit of the title compound contains two molecules; the corresponding bond lengths and angles of these two molecules agree with each other. In the solid state, the two independent molecules exist as O—H···N hydrogen-bonded dimer; the mean planes through the non-hydrogen atoms of the two molecules form a dihedral angle of 77.98 (5)°.
