Route of Synthesis (ROS)

| Conditions | Yield |
| Stage #1: C6N8O11(2-)*2K(1+) With silver nitrate In water at 20℃; for 0.5h; Stage #2: hydrazine hydrochloride In water at 60℃; for 1h; Experimental Procedure General procedure for synthesis of the salts 3-5 A solution of AgNO3 (0.169 g, 1 mmol) in 10 mL water was added to a solution of 2 (0.438 g, 1 mmol) in 10 mL water. After stirring for 30 min at room temperature, chloride salt (1.0 mmol) was added. The resulting mixture was stirred at 60° C for an additional 1 h. After removal of AgCl, the solution was evaporated in vacuo and the target product was obtained. | 75.8% |
