Li17Sb13S28was synthesized by solid‐state reaction of stoichiometric amounts of anhydrous Li2S and Sb2S3. The crystal structure of Li17Sb13S28was determined from dark‐red single crystals at room temperature. The title compound crystallizes in the monoclinic space groupC2/m(no. 12) witha=12.765(2) Å,b=11.6195(8) Å,c=9.2564(9) Å,β=119.665(6)°,V=1193.0(2) Å3, andZ=4 (data at 20 °C, lattice constants from powder diffraction). The crystal structure contains one cation site with a mixed occupation by Li and Sb, and one with an antimony split position. Antimony and sulfur form slightly distorted tetragonal bipyramidal [SbS5E] units (E=free electron pair). Six of these units are arranged around a vacancy in the anion substructure. The lone electron pairsEof the antimony(III)cations are arranged around these vacancies. Thus, a variant of the rock salt structure type with ordered vacancies in the anionic substructure results. Impedance spectroscopic measurements of Li17Sb13S28show a specific conductivity of 2.9×10−9Ω−1cm−1at 323 K and of 7.9×10−6Ω−1cm−1at 563 K, the corresponding activation energy isEA=0.4 eV below 403 K andEA=0.6 eV above. Raman spectra are dominated by the SbS stretching modes of the [SbS5] units at 315 and 341 cm−1at room temperature. Differential thermal analysis (DTA) measurements of Li17Sb13S28indicate peritectic melting at 854 K.
