SYNTHESIS AND STRUCTURE OF SURPRISINGLY STABLE TETRAKIS(TRIFLUOROMETHYL)CUPRATE(III) SALTS

CF3 groups stabilize the CuIII center in the complex anion [Cu(CF3)4]− (1). Salts of 1 with large cations are easy to prepare by oxidation of CuI‐CF3 compounds with, for example, I2. The CuIII center in 1 has approximately square‐planar coordination geometry, and the F atoms form one planar hexagon above the CuC4 plane and one below. • Cu, ◯  C,  F. (Figure Presented.)
