    • 2O (2 mmol; 0.48 g) were suspended in 5 mL of methanol. The solution was stirred for 15 min, and the AgCl precipitate was removed from the dark violet solution. This mixture was carefully poured into one H-tube leg, while 18-crown-6 (1 mmol; 0.264 g) was added in the other. The diffusion tube was filled with MeOH and left to stand. After 10 days, the dark blue prismatic crystals that grew in one of the tube legs were filtered, washed with MeOH, and dried in air. Anal. Calcd (Found) for (1): C, 29.91 (29.63); H, 4.18.
