Reaction of HAuCl 4 · 4H 2 O with the multifunctional ligand 3‐(1 H ‐1,2,4‐triazol‐1‐yl)propanamide ( 1 , TPA) afforded the polymorphic gold(III) complex AuCl 3 (TPA) ( 2 ) in 75 % yield. Thermal decomposition of the latter revealed the hydrochloride [HTPA]Cl ( 3 ). Complex 2 forms a stable monoclinic and a metastable triclinic modification. The crystal structures of both modifications feature infinite supramolecular assemblies formed by secondary Au ··· Cl bonding interactions and hydrogen bonding.
