Abstract

The preparation and characterization of a series of magnesium(II) iodide complexes incorporating -diketiminate ligands of varying steric bulk and denticity, namely, [(ArNCMe)2CH]- (Ar=phenyl, (PhNacnac), mesityl (MesNacnac), or 2,6-diisopropylphenyl (Dipp, DippNacnac)), [(DippNCtBu)2CH]- (tBuNacnac), and [(DippNCMe)(Me2NCH2CH2NCMe)CH]- (DmedaNacnac) are reported. The complexes [(PhNacnac)MgI(OEt2)], [(MesNacnac)MgI(OEt2)], [(DmedaNacnac)MgI(OEt2)], [(MesNacnac)MgI(thf)], [(DippNacnac)MgI(thf)], [(tBuNacnac)MgI], and [(tBuNacnac)MgI(DMAP)] (DMAP=4-dimethylaminopyridine) were shown to be monomeric by X-ray crystallography. In addition, the related -diketiminato beryllium and calcium iodide complexes, [(MesNacnac)BeI] and [ (DippNacnac)CaI(OEt2) 2] were prepared and crystallographically characterized.
