New seven Au‐ N ‐heterocyclic carbene (NHC) complexes have been synthesized via transmetalation from Ag‐NHC complexes. NHC salts, Ag‐NHC, and Au‐NHC were fully characterized by widely used spectroscopic techniques. The molecular crystal structures of 3b 3f clarified through the single‐crystal X‐ray diffraction method. According to analysis results, coordination geometry around Au(I) atoms in are revealed be almost linear with C–Au–Cl angle. Anticancer activity, DNA binding, xanthine oxidase...
