Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Compound 1a combines conductivity with BET surface area above 1000 m2/g, which the authors identify as unusually high for conductive MOFs.
Caveat: Comparative claim relies on literature context current to 2017.
8 · Electrical Conductivity · Linked to 2 structured results
Magnetic behaviour in 2 is likely dominated by intralayer metal-organic radical coupling and is best described tentatively as a 2D bulk ferrimagnet.
Caveat: The paper explicitly says magnetic behaviour alone cannot definitively determine dimensionality.
7 · Magnetic Properties · Figure 6 · Linked to 2 structured results
Pressed-pellet conductivity values for low-dimensional materials may be artificially low because anisotropic pathways and grain boundaries suppress transport.
Caveat: Single-crystal conductivities were not measured in this paper.
7 · Electrical Conductivity · Linked to 3 structured results
Reduction of 1 to 2 is ligand-centred rather than Fe-centred, giving [FeIII2(L3-rad)3]3- while retaining high-spin FeIII.
Caveat: Authors caution that X-ray diffraction alone is not conclusive because bond-distance changes are small; spectroscopy strengthens the assignment.
4 · Syntheses and Structures · Figure 2 · Linked to 6 structured results
Compound 2 reaches Tc = 105 K because complete ligand reduction strengthens intralayer metal-organic radical coupling.
Caveat: The authors state the magnetic dimensionality/ferrimagnet assignment is tentative from magnetic data alone.
7 · Magnetic Properties · Figure 7 · Linked to 3 structured results
Conductivity decreases from 1 to 2 because full ligand reduction removes mixed valency and a facile charge-hopping pathway.
Caveat: Mechanistic interpretation is inferred from conductivity and activation-energy trends rather than direct charge-transport imaging.
