Proton-Mediated Electron Configuration Change in High-Spin Iron(II) Porphyrinates Chuanjiang Hu Bruce C. Noll Charles E. Schulz W. Robert Scheidt 10.1021/ja055129t.s003 https://acs.figshare.com/articles/dataset/Proton_Mediated_Electron_Configuration_Change_in_High_Spin_Iron_II_Porphyrinates/3259597 The synthesis, molecular structure, and electronic structure characterization of two five-coordinate high-spin imidazolate-ligated iron(II) porphyrinates are reported. Their electronic structure, as deduced from Mössbauer spectra obtained in strong magnetic fields, is distinctly different from that of the analogous imidazole-ligated species. The resulting electronic structure models are consistent with all observed differing features in the two classes. 2005-11-02 00:00:00 structure characterization M össbauer spectra structure models
