The crystal structure was determined from dark-gray single crystals at 123 K. [Li.sub.3][Sb.sub.11]S.sub.18 crystallizes in the triclinic space group P\bar1P1A[macron] with a = 8.871(1) A, b = 11.993(1) A, c = 15.407(1) A, [alpha] = 80.014(5)[degrees], [beta] = 73.599(5)[degrees], I[sup.3] = 77.443(5)[degrees], V = 1523.9(2) A.sup.3, and Z = 2 (data at 123 K). Both metals have a distorted octahedral coordination by sulfur. These octahedra are arranged in two different types of alternating layers. Strands of trans edge sharing octahedra LiS.sub.6 and octahedra SbS.sub.6 form heterocubane units [LiSb.sub.3]S.sub.4, which are condensed to a rock salt type layer one. Layer two consists mainly of SbS.sub.6-units also packed in a rock salt motif. Some of the antimony atoms are replaced by lithium in a systematic way. In total, a deficient rock salt type structure results for [Li.sub.3][Sb.sub.11]S.sub.18.
