Crystal structure of the gold(I) complex [Au(tfp)Cl] with tfp =(C4H3O)(3)P

The Au(I) complex [Au(tfp)Cl] with tfp = (C4H3O)3P has been prepared and characterised. It crystallises in the monoclinic P21/n space group with z = 4, a = 9.837(3), b = 12.684(4), c = 11.103(5)A° , β = 91.58(2)◦ and V = 1384.8(2)°A3. The structure of the complex consists of molecules connected in head-to-tail dimers by a metal-halogen contact as generally found in analogus complexes of lighter coinage metals. The typical feature of halogen gold compounds, the Au Au interaction, seems prevented by the bulk of the tfp ligand
