Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Compound 1 is an electrically bistable semiconductor with two hysteretic transitions near room temperature and at higher temperature.
Caveat: Transport values are crystal-dependent and successive cycles increase resistivity, probably due to microbreaks.
1 · Abstract · Figure 4; Figure 6 · Linked to 5 structured results
The authors could not perform detailed single-crystal structural analysis of the resistivity transitions because the available single crystals had low crystallinity.

Compound 1 is reported as the first example of a 1D coordination polymer containing iron dithiolato entities and the first with K+ counterions among reported [Fe(dithiolato)2] structures.
Caveat: Novelty claim depends on authors' 2012 CCDC search and literature context.

Compound 1 contains low-spin S = 1/2 Fe(III) dimers with antiferromagnetic Fe-Fe coupling.
Caveat: The S = 3/2 dimer model also fits reasonably but gives an unrealistic g value according to the authors.

The two resistivity transitions are attributed to slight structural changes that modify cation-anion or Cl...Cl interactions and orbital overlap.
Caveat: A detailed single-crystal structural analysis of the transitions was not feasible because of low crystallinity.
6 · Results and Discussion - Electrical Properties · Figure 5 · Linked to 6 structured results
The authors assign electron delocalisation primarily to interdimer Cl...Cl halogen bridges rather than through K+ cations.
Caveat: Mechanism is inferential; authors note electrical conductivity through this kind of Cl...Cl bridge had not previously been observed.
