Seeing luminescence appear as crystals crumble. Isolation and subsequent self-association of individual [(C₆H₁₁NC)₂Au]⁺ ions in crystals.

ABSTRACT: Non-luminescent, isostructural crystals of [(C₆H₁₁NC)₂Au](EF₆)·C₆H₆ (E = As, Sb) lose benzene upon standing in air to produce green luminescent (E = As) or blue luminescent (E = Sb) powders. Previous studies have shown that the two-coordinate cation, [(C₆H₁₁NC)₂Au]⁺, self-associates to form luminescent crystals that contain linear or nearly linear chains of cations and display unusual polymorphic, vapochromic, and/or thermochromic properties. Here, we report the formation of non-luminescent crystalline salts in which individual [(C₆H₁₁NC)₂Au]⁺ ions are isolated from one another. In [(C₆H₁₁NC)₂Au](BArF
