15. 2O (0.061 g, 0.257 mmol) was added; the resulting dark blue solution was stirred for 10 minutes. Reddish brown micro crystals were precipitated by adding tetrabutylammonium bromide (0.2 g, 0.62 mmol); the microcrystals were filtered, washed with water followed by diethyl ether and dried at room temperature. It was recrystallized from acetonitrile solution by diffusing diethyl ether. Yield: 0.250 g (52.0% based on Ni).
