A vacuum sublimation apparatus with a continuous-temperature gradient (30–280 °C) along the glass tube (60–0 cm) at 10<SUP>−2</SUP> and 10<SUP>−1</SUP> Torr (1 Torr=133.322 Pa) was used. 8-Quinolinol (Oxine, ox) and its Mo<SUP>6+</SUP> and W<SUP>6+</SUP> chelates (MoO<SUB>2</SUB>(ox)<SUB>2</SUB> and WO<SUB>2</SUB>(ox)<SUB>2</SUB>) in milligram amounts were sublimed without any thermal decomposition. The Mo<SUP>6+</SUP> chelate (orange yellow) forms large, rectangular crystals in the crossed state, while the W<SUP>6+</SUP> chelate (pale yellow) forms small, rectangular crystals in the scattered states after vacuum sublimation.
