A series of six‐ and seven‐membered expanded‐ring N ‐heterocyclic carbene (er‐NHC) gold(I) complexes has been synthesized using different synthetic approaches. Complexes with weakly coordinating anions [(er‐NHC)AuX] (X − =BF 4 − , NTf 2 − , OTf − ) were generated in solution. According to their 13 C NMR spectra, the ionic character of the complexes increases in the order X − =Cl −
