Abstract/Summary:
The area of mixed ligand complexes of the group 2 metals is fairly undeveloped. This work describes the synthesis of mixed ligand complexes of the heavier group 2 metals stabilized by a novel, asymmetric, and very bulky beta-diketiminato ligand (2,4,6-Me3C6H3)NC( tBu)CH2C(tBu)N(2,6- iPr2C6H3)], LAr'Ar ''. The ligand is coordinated in a eta5-fashion about the metal centers. In addition, a Ba complex with a less bulky beta-diketiminato ligand having an ethyl group at each nitrogen atom was also prepared. This complex forms a dimeric structure that adapts a mu-eta2:eta 5 coordination mode on the metal center. This complex, however, was not volatile under sublimation conditions. All complexes have been prepared and characterized by spectral and analytical methods, as well as X-ray crystallography.
