During an investigation of the interaction of the components in the Li–SnSi system, the existence of seven binary compounds was confirmed in the Li–Sn system by means of X-ray powder diffraction. A continuous series of solid solutions was found between the Li17Sn4 and Li17Si4 binary intermetallides with Li17Pb4-type structure. The cell parameters within the solid solutions change approximately according to Vegard’s law (Li17Sn4-õSiõ (õ = 0‑4), à = 1.9714(1)-1.8718(1) nm). The variation of the lattice parameters within the limited solid solutions based on LiSn (up to 10 at.%) and Li7Sn3 (up to 5 at.%) binary compounds was also determined.
