In an effort to develop new MOCVD precursors, mixed-ligand metal-organic complexes, bis (acetylacetonato-k(2)O,O%26apos;) (2,2%26apos;-bipyridine-k(2)N,N%26apos;) magnesium(II), and his (acetylacetonato-k(2)O,O%26apos;) (1,10-phenanthroline-k(2)N,N%26apos;) magnesium(II) were synthesized. Spectroscopic characterization and crystal structures confirmed them to be monomeric and stable complexes. Crystal structure analysis suggests in each of the magnesium(II) complexes, the metal center has a distorted octahedral coordination geometry. Thermo-gravimetric analysis (TGA/DTA) suggests that these complexes are volatile and thermally stable. The thermal characteristics of newly designed complexes make them attractive precursors for MOCVD applications.
