Five pairs of perfluorophenyl‐ and phenyl‐substituted tris(pyrazol‐1‐yl)borate complexes have been prepared and thoroughly investigated, namely, [(C 6 R′ 5 Bpz 3 ) 2 Fe], [(C 6 R′ 5 Bpz 3 ) 2 Cu], [(C 6 R′ 5 Bpz 3 )Mn(CO) 3 ], K[(C 6 R′ 5 Bpz 3 )Mo(CO) 3 ], and [(C 6 R′ 5 Bpz 3 )Mo(CO) 2 (2‐methallyl)] (R′ = F, H; pz = pyrazol‐1‐yl). X‐ray crystal structure analyses and IR spectroscopical measurements reveal only a minor influence of the spectator substituents on the corresponding parameters. In contrast, significant differences between the redox potentials of the fluorinated and non‐fluorinated species are evident in their cyclic voltammograms. Large differences have been found between the crystal packings of the complexes with perfluorinated and non‐fluorinated phenyl rings.
