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

摘要

Three complexes containing the dipyrimidine-2-thiolategold(I) anion, [Au(2-pymS)(2)]-, (2-pymSH = pyrimidine-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 (H- 1 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.
