Non-stoichiometry of tris(8-hydroxyquinoline) aluminium: is it possible?

Abstract

The dependence of the 8-hydroxyquinoline (8-Hq) vapour pressure on temperature, log <italic>P</italic>_8-Hq [Torr] = 8.4249 − 2963.5/<italic>T</italic>, (386–482 K) was measured by Bourdon manometer technique. Tris(8-hydroxyquinoline) aluminum crystals were grown under controlled <italic>P</italic>_8-Hq [0.1–11.3 Torr] and their cell parameters were measured.
