Crystal structure of chlorido­[trans-1-(di­phenyl­phosphane­thioyl-κS)-2-(di­phenyl­phosphano­yl)ethene]gold(I) di­chloro­methane hemisolvate1

The title compound, [AuCl(C26H22OP2S)]·0.5CH2Cl2, crystallizes with a trans-O—P⋯P—S geometry of the groups either side of the C=C double bond, which prevents any intra­molecular contact between the Au and O atoms. The AuI atom exhibits a nearly linear coordination [Cl—Au—S = 177.55 (4)°]. The mol­ecules associate to form broad ribbons parallel to the c axis via two C—H⋯O, one C—H⋯Cl(Au) and one Au⋯Cl inter­action.
