Au2cl6

The compound Au2Cl6 is a coordination complex consisting of two gold atoms coordinated to six chloride anions. Each gold atom is in a square-planar environment with four chloride ligands arranged around it in a plane, and two additional chloride ligands above and below the plane.

The molecule has D4h symmetry, which means that it has four-fold rotational symmetry about its central axis and symmetry elements of reflection about two perpendicular planes.

The compound is insoluble in water but soluble in organic solvents such as ethanol and acetone. It is typically prepared by reacting gold(III) chloride with metallic gold in the presence of hydrochloric acid.

Au2Cl6 has several interesting properties, including its use as a catalyst for various organic reactions and its ability to form self-assembled monolayers on gold surfaces. It also exhibits luminescence in solutions and can be used as a potential material for optical devices.
