Procedure

First, 2.4 g (15mmol) of 2-methyl-8-quinolinol (Wako Pure Chemical Industries, Ltd.) was dissolved in 100 ml of ethanol, and 0.88 g (5 mmol) of trihydric gallium chloride (Kishida Chemical Co., Ltd.) was dissolved in 200 ml of demineralized water. The 2-methyl-8-quinolinol ethanol solution thus produced was little by little added to the gallium chloride aqueous solution with stirring. Immediately, they began to react with each other, light green precipitates being observed. The stirring was continued for about 15 minutes until finally the precipitates were suction-filtered. They were completely dried and purified with the use of a sublimation apparatus (H. J. Wagner, R. O. Loutfy, and C. K. Hsiao; J. Mater. Sci. 172781 (1982)), which employs train sublimation method.
