Description
Sarah Costa and co-authors grow, in a 2024 study, five new gold complexes that pair two gold ions in mixed embrace. A bridging ligand built on two phosphorus arms holds the pair close. In gold chemistry, the number of partners each ion carries, two or three, shapes the whole structure, and mixed pairs are rare curiosities.
Crystal structures tell the story of each salt. One complex holds two three-coordinate golds in a symmetric frame. Three others carry an odd couple: a two-coordinate gold bound to a three-coordinate one through the weak gold-gold attraction called aurophilic. In the fifth, a chloride ion hovers evenly between the two golds at long range. All five glow under ultraviolet light. The authors present the set as a small zoo of how one ligand can stage very different partnerships between the same two metals.
