Abstract

The anisole-substituted silyl-amide anion, [N(SiMe2{C6H4-2-OMe})2]− (L), has been used as a pincer-type ligand in coordination chemistry. X-ray diffraction data for the lithium salt shows a trimetallic structure consisting of two equivalents of Li(L) that sequester a molecule of LiCl. The potassium salt K(L) is dimeric in the solid-state with bridging amide ligands. Each structure shows chelation of both O-donor groups to the electropositive metal. In contrast, the titanium compound Ti(L)Cl3 is four-coordinate with a monodentate amide. The zirconium compound Zr(L)2Cl2 is monometallic with a six-coordinate metal and two N,O-bidentate amides.
