Three monomeric compounds containing the dipyrimidine-2-thiolategold(I) anion

Abstract

Abstract Three complexes containing the dipyrimidine-2-thiolategold(I) anion, [Au(2-pymS)2]-, (2-pymSH\u202f=\u202fpyrimidine-2-thione), Na[Au(2-pymS)2] (1), N(C2H5)4[Au(2-pymS)2] (2), and H[Au(2-pymS)2] (3), have been synthesized and characterized by spectroscopy (1H NMR, IR, and ESI –MS) and by X-ray crystallography. The monomeric compounds are easily solubilized in water and in various polar organic solvents. The complex anion shows a linear S Au S geometry in all three compounds, but the counter cations create a different space group for each compound and also deter Au Au interactions.
