Abstract Dimethyl 5‐aminoisophthalate, which is a building block of amino‐substituted tetralactam macrocycles, was used as ligand in gold(I) chemistry to form model complexes for macrocyclic gold compounds. Reaction of dimethyl 5‐aminoisophthalate with chlorodiphenylphosphine gave the diphosphine compound dimethyl 5‐[ N , N ‐bis(diphenylphosphanyl)amino]isophthalate (dmbpaip). This compound can further be reacted with [AuCl(tht)] (tht = tetrahydrothiophene) to give the dinuclear complex [Au 2 Cl 2 (dmbpaip)]. In contrast, treatment of dmbpaip with [Au(tht) 2 ]ClO 4 resulted in the ionic compound [Au 2 (dmbpaip) 2 ](ClO 4 ) 2 in which the cation forms an eight‐membered Au 2 P 4 N 2 heterocycle. In both gold(I) compounds Au···Au interactions are observed. All new compounds were characterized by single‐crystal X‐ray diffraction.
