Chloro(tetrahydrothiophene)gold(I), abbreviated (tht)AuCl, is a coordination complex of gold. Like the dimethyl sulfide analog, this compound is used as an entry point to gold chemistry. The tetrahydrothiophene ligand is labile and is readily substituted with other stronger ligands.

Preparation

This compound may be prepared by the reduction of tetrachloroauric acid with tetrahydrothiophene:^[1]

HAuCl₄ + 2 SC₄H₈ + H₂O → AuCl(SC₄H₈) + OSC₄H₈ + 3 HCl

The complex adopts a linear coordination geometry, as is typical of many gold(I) compounds. It crystallizes in the orthorhombic space group Pmc2₁ with a = 6.540(1) Å, b = 8.192(1) Å, c = 12.794(3) Å with Z = 4 formula units per unit cell. The bromide congener is isostructural.^[2]

It is somewhat less thermally labile compared to (Me₂S)AuCl, but is still sensitive to temperature and light.
