摘要：

In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)(2)(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetrahedral geometries. The Li+ ion is N, N'-chelated by the N-silylated amido ligand, with Li-N = 2.015 (5) and 2.074 (5) angstrom. The two amido ligands are arranged cis to each other. The molecule exhibits a twofold rotational symmetry operation along the Li-Na axis. The Na + ion is coordinated by two N atoms from the tetramethylethylenediamine ligand [Na-N = 2.553 (4) angstrom] 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 angstrom(3) there is no inclusion of solvent molecules.
