Figure 19
One formula unit of 1,1,3,3-tetraphenyl-1,3-dihydro-2,1,3-benzothiadiphosphole-1,3-diium bromide tetrabromidoaurate(III) dichloromethane hemisolvate (Taouss & Jones, 2011

), excluding solvent, showing the short S⋯Br⁻ and Au—Br⋯π contacts (full and open dashed bonds respectively); only the former were discussed at the time. The ensemble displays crystallographic inversion symmetry. The other independent formula unit shows no Br⋯π contacts, but is instead involved in Br⋯Cl contacts to the solvent molecule.
