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.
The two materials are presented as rare conducting magnetic MOFs and the first examples, according to the authors, delaminated into few-layer nanosheets.
Caveat: No electrical conductivity was reported for the exfoliated nanosheet films themselves.
p006-p007 · Conclusions · Figure 8 · Linked to 8 structured results
Compounds 1 and 2 are mixed-valence Fe(II)/Fe(III) 2D MOFs with average Fe oxidation state +2.5 and oxidised anilato ligands.
Caveat: Fe(II)/Fe(III) centres are crystallographically equivalent at 120 K because the electron is delocalised.
p003-p004 · Synthesis and Structure · Figure S4; Table S1 · Linked to 6 structured results
Electrical transport is strongly anisotropic, with in-plane conductivity exceeding through-layer conductivity by factors of ca. 300 for compound 1 and ca. 500 for compound 2.
Caveat: Ratios are based on averaged two-contact measurements on small single crystals.
p005 · Electrical Conductivity · Table S2 · Linked to 6 structured results
The Cl derivative is about one order of magnitude more conductive parallel to the layers than the Br derivative, consistent with greater electron delocalisation in compound 1.
Caveat: Conductivities were measured by a two-contact method on single crystals; contact effects are not separately deconvoluted.
p005-p007 · Electrical Conductivity; Conclusions · Table S2 · Linked to 4 structured results
Electron delocalisation between Fe centres enables both semiconducting transport and ferromagnetic coupling via double exchange.
Caveat: The double-exchange mechanism is the authors' interpretation rather than a directly measured microscopic parameter.
