YieldReaction ConditionsOperation in experiment
66.2% For complex 1, a mixture of Co(NO3)26H2O (0.029 g, 0.1mmol), H2L (0.027 g, 0.1 mmol), btrb (0.024 g, 0.1 mmol),acetonitrile (6 mL) and DMF (3 mL) were stirred for 0.5 hunder ultrasonic conditions. And then the solution was transformedinto the Teflon-lined stainless steel vessel (15 mL),sealed, and heated to 130 C for 3 days. Subsequently, the vesselwas cooled to the room temperature at the degree of 5Ch1. Pink block crystals of 1 were collected with the yieldof 66.2% (based on Co(NO3)26H2O). Anal.
