Figure 5
k3-weighted EXAFS (top panels) and modulus of phase-corrected Fourier transform (bottom panels) of experimental values (solid lines) and simulations (dashed lines, parameters in Table 3) of (a) [Zn(imidazole)4](ClO4)2 (3), (b) Zn(imidazole)2(acetate)2 (4), and (c) di-(L-histidino)zinc(II) dihydrate (5). Insets of bottom panels: final geometry of imidazole ring after refinement, with Zn as the central atom, N atoms (1) and (4), and C atoms (2), (3) and (5). |
