a X-ray PDF in the form of D(r) of dg-MUV-29-bim0.48, dg-MUV-29-bim0.18, ag-MUV-24 and IMIDFE. b Schematic representation of the benzimidazolate bridge coordinated to two FeII centers and the connectivity between tetrahedral FeII ions with benzimidazolate linkers. Orange spheres represent Fe atoms, blue spheres represent nitrogen atoms, and black spheres represent carbon atoms. Hydrogen atoms have been omitted for clarity. Mössbauer spectra of dg-MUV-29-bim0.48 (c) ag-MUV-24 (d) and IMIDFE (e) samples, displayed with lines overlaid on the experimental data. These lines represent the sum of doublets and sextets, or distributions of quadrupole splitting (QS) (see Table S2), and are slightly shifted for clarity. Source data are provided as a Source Data file.
