Procedure

Lithium hydroxide monohydrate (0.839 g, 0.02 mmol), boric acid (1.236 g, 0.02 mmol), and 2 equivalents of 3,4-dihydroxybenzonitrile (5.4 g, 0.04 mmol) were mixed in 4 ml water. The mixture was heated to near boiling for few minutes till a clear pink colored solution was obtained. Upon cooling to room temperature a white solid was formed. The supernatant solution was decanted and the solid was recrystallized from small quantity of hot water. After drying in an oven, lithium bis(3,4-dihydroxybenzonitrile) borate was isolated as a white powder. Yield=5.3 g (93%), mp>300° C.
