Aurophilic interaction leads to distortion of the ten-membered centrosymmetric Au2As2S2C4 ring in [Au2{μ-(SC6H4-2-AsPh2)-κS,κAs}2]

The title compound [Au2{μ-(SC6H4-2-AsPh2)-κS,κAs}2] consists of a dinuclear unit with two AsS– ligands (AsSH = 1-AsPh2-2-SHC6H4) bridging the gold(I) atoms. Each gold(I) atom is coordinated by a sulfur atom from one ligand and one arsenic atom from the other ligand with formation of a ten-membered centrosymmetric Au2As2S2C4 ring. The deviation of the As–Au–S fragment from linear geometry is associated with the presence of a short gold···gold contact.
