Abstract
A three-dimensional X-ray structure analysis by the heavy-atom method of 2SbCl3·C6H4Me2 is described. Crystals are monoclinic, space group P21/c, a= 9.13(4), b= 8.44(2), c= 12.79(4)Å, β= 125.35(20)°, Z= 2. Least-squares refinement of photographic data led to R 0.11 for 920 independent reflections. The structure is essentially layered, with alternate SbCl3 and p-xylene layers. The SbCl3 molecules occur with an ‘incipient dimer’ configuration. Sb–Cl bond distances are 2.30, 2.32, and 2.37 Å. The shortest Sb ⋯ C distance is 3.18 Å.Keywords
