The reaction between an angular bis-imidazolidinium salt and [AuCl(SMe)2] allowed the preparation of a
discrete digold complex, with a rigid angular bridging bis-imidazolindiylidene ligand. This complex reacts with a
diethynylcarbazole to afford a tetragold cyclophane that contains two bis-imidazolindiylidenes and two carbazolyl-diethynyl
ligands. Both the dimetallic and the tetrametallic complexes have been characterized by spectroscopic techniques and by singlecrystal X-ray diffraction. Due to the geometric constraints of the ligands, the cyclophane deviates from the expected planarity
and shows a twisted structure. The work demonstrates that the rigid angular di-NHC ligand is a suitable scaffold for the reliable
construction of organometallic-based metallosupramolecular assemblies. [-]
