Abstract

Abstract: A mononuclear bis(NHC)/Au I (NHC=N‐heterocyclic carbene) cationic complex with a rigid bis(phosphane)‐functionalized NHC ligand (PCNHC P) was used to construct linear Au3 and Ag2 Au arrays, a Au5 cluster with two intersecting crosslike Au3 arrays, and an unprecedented Cu6 complex with two parallel Cu3 arrays. The impact of metallophilic interactions on photoluminescence was studied experimentally. Abstract : Crossing paths : A mononuclear bis(NHC)/Au I (NHC=N‐heterocyclic carbene) cationic complex with a rigid bis(phosphane)‐functionalized NHC ligand (PCNHC P) provides access to unique Au, Au/Ag, and Cu arrays. These arrays display metallophilicity‐based photoluminescence.
