Heteroleptic magnesium complexes containing amidinate and aminoalkoxy ligands

New heteroleptic magnesium complexes, [Mg(dmamp)(η2-MeC(NEt)(NtBu))]2 (1), [Mg(dmamp)(η2-MeC(NiPr)2]2 (2), and [Mg(dmamp)(η2-MeC(NtBu)2]2 (3), containing a combination of amidinate and aminoalkoxy ligands were synthesized and characterized by NMR, FT-IR, elemental analysis, and thermogravimetric analysis (TGA). The single-crystal X-ray diffraction study of these complexes (1–3) reveals that all complexes were formed as dimers where the aminoalkoxy ligand acts as the bridge between the two metal centers.

Design and synthesis of new heteroleptic magnesium complexes, containing aminoalkoxy and amidinate ligands were demonstrated. The complexes formed as dimers, where aminoalkoxy ligands play the role of bridging two magnesium metal centers.Figure optionsDownload as PowerPoint slide
