The crystal structure of the complex 2SbCl₃.p-xylene (space group: P2₁/c; a=9.13Å, b=8.44Å, c=12.79A, β=125°21') was investigated at low temperatures, and it proves to be a layer structure with packing p-xylene molecules. The compound C₅H₅NH⁺ Sbcl₄⁻ (space group; C2/c; a=13.12Å, b=13.07Å, c= 7.44Å, β =122°19') was identified as a hydrolysis product of' the Sbcl₃/pyridine system by means of a partial structure analysis. The complex 2Sbcl₃.C₅H₅N (space group: Pca2₁; a=26.14Å, b=11.93Å, o=7.51Å) was prepared and its structure elucidated. Its general structural features include an infinite Sb - C1 chain, pyridine ligands attached to the antimony atom, and the presence, in addition, of a "solvating" pyridine molecule. The complex 2Sbcl₃.C₅H₅N (space group; P1; a=10.93A, b=8.92Å, c=9.30Å, ∝ = 106°48’, β = 192°48’, ⋈ = 116 °36’) was prepared. This has an extensively bridged Sb - Cl system and non-bonding pyridine molecules, occurring in alternate layers. The complex SbCl₃.C₅H₅N (space group: P2₁/c; a=13.00Å., b=17.87Å, c=12.17Å, β=121°11') was prepared.
