Alkaline earth metal complexes diacetamide

Few stable complexes of alkali metals have been reported. Complexes of the alkali metals with j -diketone derivaties, o-nitrophenol, and sali-cylaldehyde have been described in the literature.The sodium compounds ranged from hydrated ionic salts such as Na (acac)-2 H2O to adducts like Na(Sal) HSal (HSal = Salicylaldehyde). PfeiflFer and others have reported the isolation of a complex of sodium perchlorate with 1,10-phenan-throline. Brady and Badger have presented evidence for chelation in sodium salts of o-hydroxybenzaldehydes. More recently, Popp and Joesten have isolated and characterized a number of alkali metal and alkaline earth metal salts with the ligand octamethylpyrophosphoramide (OMPA). Gentile and co-workers have also reported complexes of diacetamide with alkali and alkaline earth metal salts.
