Catena-Poly[lithium(I)-μ-1-tert-butyl-3-(3-pyridyl)-N,N′-bis(trimethylsilyl)propane-1,3-diiminato

Abstract

The title compound, [Li(C18H32N3Si2)]n, is a convenient ligand-transfer reagent for the synthesis of metal complexes of this β-diketiminate ligand. Lithium is coordinated by three N atoms: two are in the delocalized NCCCN fragment and one is from the pyridyl in an adjacent mol­ecule. Owing to the coordination of lithium by the pyridyl N atom, the crystal structure displays a one-dimensional polymeric structure.
