title: Bis[μ-N-(tert-butyl-dimethyl-sil-yl)quinolin-8-aminato-1:2κ(2) N (1),N (8):N (8)](N,N,N',N'-tetra-methyl-ethane-1,2-diamine-1κ(2) N,N')lithiumsodium.
abstract: In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)2(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetra-hedral geometries. The Li(+) ion is N,N'-chelated by the N-silylated amido ligand, with Li-N = 2.015 (5) and 2.074 (5) Å. The two amido ligands are arranged cis to each other. The mol-ecule exhibits a twofold rotational symmetry operation along the Li-Na axis. The Na(+) ion is coordinated by two N atoms from the tetra-methyl-ethylenediamine ligand [Na-N = 2.553 (4) Å] and shares two amido N atoms from the N-silylated amido ligands with the Li(+) ion. Although the crystal structure contains voids with an approximate volume of 50 Å(3) there is no inclusion of solvent mol-ecules.
