[Au2Ag4L4]2⊖, [Au2Cu4L4]2⊖, [Au3Cu3L4]2⊖, [Cu4L3]2⊖, and [Ag9L6]3⊖ (L = ethane‐1,2‐dithiolate)—Novel Homoleptic Complexes of the Coinage Metals, including the First Heteronuclear Metal Thiolates

The heteronuclear M6S8 cages A describe the structures of 1 and 2, which are formed from AgNO3 and CuCl2 or CuCl, respectively, ethanedithiolate (L), and [AuBr2]⊖. A homonuclear analogue of A is still unknown, since the combination of linear and trigonal-planar coordination is difficult to attain with a heavy element. The structure 3 can be regarded as a distorted sulfur icosahedron enclosing a likewise distorted silver cube with a further silver atom at the center.
