Alkali Metal Complexes. Binuclear Alkali Metal Complexes with Magnesium(II) and Zinc(II) Acetylacetonates

Chemistry Department, Patna University, Patna-800 005 Manuscript received 16 June 1983, accepted 30 April 1985 Heterobinuclear alkali metal complexes have been synthesised by treating metal chelates of magnesium and zinc acetylacetonates with alkali metal salts of 1-nitroso­-2-naphthol and 8-hydroxyquinoline in ethanol/benzene-ethanol mixture. The general formula of the complex has been established as [Mα (acac)2 MbL], where Mα -magnesium or zinc, acac- acetylacetonate, and MbL -Li, Na and K salt of 1-nitroso-2-naphthol and 8-hydroxyquinoline. The infrared stretching bands of C ―O in adducts reveal the presence of bridged and unbridged oxygen atoms, and the bridging has been assigned to be due to attachment of oxygen atoms with alkali metal ions
