Synthesis and X-ray crystal structure of a 1,1-dithiolate cluster anion containing an Ag61 octahedron [Ag61{s2cc(cn)2}6]6–

The existence of the novel title anion, despite its high electrical charge and the surprising fact that its ag6S12core has the same size as that in the uncharged molecule [Ag61{S2C-N(C3H7)2}6],1 must be due to Ag–Ag interactions.
