Zinc acetate dihydrate (1.0 g) was dissolved in 75 ml. of hot methanol and 1.4 g of 8-hydroxyquinoline was added to the homogeneous solution. A yellow precipitate formed after a few minutes and the solution was stirred at reflux for 3 hours. The solution was allowed to cool and the precipitate was isolated by filtration and washed with methanol and petroleum ether. After air drying, 1.44 g of bis(8-hydroxyquinolinato)zinc was obtained as a bright yellow solid.
