were structurally characterized by single-crystal X-ray diffraction. Infrared spectroscopic analysis of the substituted CpMn(CO)3 complexes showed a linear increase of 5 cm−1 in the A-symmteric stretching frequency for each C7F7 substituent, compared to the analogous value of 4 cm−1 reported earlier for each pentafluorophenyl (C6F5) substituent. Solution voltammetric analysis of the substituted ferrocene
