Procedure

0.5 g of 1,10-phenanthroline (made by Wako Pure Chemical Industries, Ltd.) and 80 ml of distilled water were put in a 300-ml glass-made reaction vessel equipped with a reflux condenser, and the mixture was heated at 60° C. to dissolve the phenanthroline and cooled to room temperature. While the solution was stirred, a solution obtained by dissolving 1 g of tetrachloroauric acid (III) tetrahydrate in 17.2 ml of distilled water was gradually added dropwise over a period of 30 minutes. After completion of the dropwise addition, the temperature was raised to 110° C., the mixture was refluxed for 5 hours, and, then, 150 g of ammonium chloride was added to the resulting reaction solution to deposit orange powder. The deposited powder was filtered, washed with cold methanol and then with cold diethyl ether, and then dried to obtain 0.79 g of a gold-phenanthroline complex (hereinafter abbreviated as [Au(phen)Cl2]+Cl—).
