Synthesis and characterization of the copper(I)carbonyl complex of flu
orinated tris(pyrazolyl)borate ligand, [HB(3,5-(CF3)(2)Pz)(3)](-) (whe
re HB(3,5-(CF3)(2)Pz)(3) = ydrotris(3,5-bis(trifluoromethyl)pyrazolyl)
borate) is reported. The CO stretching frequency of the [HB-(3,5-(CF3)
(2)Pz)(3)]CuCO is one of the highest observed for a structurally chara
cterized copper complex.
