k2-weighted Fourier transforms (FT) of organozirconium complex Zr K-edge EXAFS. (A) k2-weighted Fourier transforms of neat Cp2ZrH2 (complex A). Red, Δk = 2.5–10.0 Å−1 data; blue, fit (NZr-Cp = 10.1 at 2.52 Å) for ΔR = 1.4–2.6 Å; solid line, FT magnitude; dotted line, FT imaginary part. (B) k2-weighted Fourier transform of the Zr K-edge EXAFS of B/AlS − B. Red, Δk = 2.5–10.2 Å−1 data; blue, fit (NZr-O = 2.1 at 2.37 Å) for ΔR = 1.5–2.6 Å; solid line, FT magnitude; dotted line, FT imaginary part. (C) Zr K-edge XANES from 17.96 to 18.04 keV. Red, C/AlS + benzene (Eo = 18.0013 keV); blue, C/AlS (Eo = 18.0005 keV). (D) k2-weighted Fourier transform of the Zr K-edge difference EXAFS of C·C6H6/AlS – C/AlS. Red, Δk = 2.7–10.6 Å−1 data; blue, fit for ΔR = 1.6–2.3 Å (NZr-Bz = 3.0 at 2.35 Å); solid line, FT magnitude; dotted line, FT imaginary part.
