Synthesis and Structure of Surprisingly Stable Tetrakis(trifluoromethyl)cuprate(III) Salts

Key Points

• The aim is to explore the stability and structural features of tetrakis(trifluoromethyl)cuprate(III) salts.
• Synthesis of salts through oxidation of CuI-CF3 compounds with iodine (I2).
• Characterization of coordination geometry with emphasis on approximately square-planar arrangement.
• The CuIII center in the complex anion [Cu(CF3)4]− exhibits significant stability.
• The F atoms are organized in a planar hexagon around the CuC4 plane.
