Abstract

Abstract : 1, 8-Bis(gold(i )-ethynyl)anthracene units find stabilisation by maximising aurophilic contacts under formation of macrocyclic anions linked to cationic gold(i ) fragments. Abstract : Two phosphane–gold(i ) functions (with tri( para -tolyl)- or tri- n -butylphosphane) were attached to a 1, 8-diethynylanthracene backbone. The ligand size prevents direct interaction between the gold atoms, but the initial products rearrange to form macrocyclic anions comprising two 1, 8-diethynylanthracene and two gold units, linked to cationic gold(i ) fragments by maximising aurophilic interactions.
