Abstract

Abstract: A new protocol for the synthesis of protic bis(N‐heterocyclic carbene) complexes of Au I by a stepwise metal‐controlled coupling of isocyanide and propargylamine is described. They are used as tectons for the construction of supramolecular architectures through metalation and self‐assembly. Notably a unique polymeric chain of Cu I with alternate Au I /bis(imidazolate) bridging scaffolds and strong unsupported Cu I –Cu I interactions has been generated, as well as a 28‐metal‐atoms cluster containing a nanopiece of Cu2 O trapped by peripheral Au I /bis(imidazolate) moieties. Abstract : Robust golden architectures : Gold(I) and NaH promote double coupling of isocyanide and propargylamine to give protic Au I /(NHC)2 species, which upon metalation are used in the construction of supramolecular architectures containing a polymeric chain of Cu I and a nanoscopic piece of cuprite (see scheme).
