%X 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¡ä-chelated by the N-silylated amido ligand, with Li¡ªN = 2.015 (5) and 2.074 (5)  . The two amido ligands are arranged cis to each other. The molecule exhibits a twofold rotational symmetry operation along the Li¨CNa axis. The Na+ ion is coordinated by two N atoms from the tetramethylethylenediamine ligand [Na¡ªN = 2.553 (4)  ] 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  3 there is no inclusion of solvent molecules.
