Bis{[mu]4-N-[phen­yl(pyridin-2-yl­aza­nid­yl)meth­yl]pyridin-2-aminido}tetra­kis(tetra­hydro­furan)­tetra­lithium

Abstract: The title complex, [Li4(C17H14N4)2(C4H8O)4], bears a novel tetra­dentate di­amido ligand. In the tetra­nuclear centrosymmetric complex mol­ecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li+ cations are coord­inated by four N (ligand) and one O (tetra­hydro­furan, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li+ cations are in distorted tetra­hedral environments consisting of three N (ligand) and one O (THF) atoms. The Li-N bond lengths vary from 2.020 (7) to 2.441 (6)Å.
