Phosphine gold(I) aryl acetylide complexes equipped with a central bis(urea) moiety form 1D hydrogen‐bonded polymeric assemblies in solution that do not display any optical activity. Chiral co‐assemblies are formed by simple addition of an enantiopure (metal‐free) complementary monomer. Although exhibiting an intrinsically achiral linear geometry, the gold(I) aryl acetylide fragment is located in the chiral environment displayed by the hydrogen‐bonded co‐assemblies, as demonstrated by induced circular dichroism (ICD).
