Figure 1.
Zero-field Mössbauer spectra (80 K) of A) crude material isolated from reaction of iron(III) perchlorate, sodium hydroxide, and R3TPA; B) compound 2; C) compound 10a; and D) compound 10b. Spectrum A was best fit to three quadrupole doublets, whereas those of B, C, and D were adequately modeled with one-site fits. Raw data are in black, simulated fits are in green, and individual sites are in blue, yellow, and red.
