Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ag-BHT film conductivity up to 250 S cm^-1 is reported as the highest value for Ag-based coordination polymers.
Caveat: Record claim is within the literature context cited by the authors, not independently benchmarked here.

No gas sorption, BET surface area, pore-size, or porosity measurement was reported in the supplied main article or SI.
Caveat: Based on full text/SI supplied for extraction; associated CIF was not supplied.
S2-S3 · Contents
Ag-BHT has a lamellar structure with alternately stacked two-dimensional Ag-S networks and one-dimensional metal-dithiolene polymer layers.
Caveat: CIF was not supplied locally; assignment is based on main article and SI structure tables/figures.

Pristine Ag-BHT is described as a degenerate semiconductor because DFT gives a band gap but the Fermi level cuts the valence band, consistent with the UPS Fermi edge.
Caveat: The proposed in situ oxidation mechanism is inferred from charge balance and reaction environment rather than directly quantified.

Chemical reduction with LiBHEt3 converts Ag-BHT from a highly conducting degenerate semiconductor to a lower-conductivity semiconductor while retaining the crystal framework.
Caveat: Reduction recipe is vague, and lithium location is unresolved.

Projected DOS indicates the two-dimensional Ag-S network is the preferred charge-transport path in Ag-BHT.
Caveat: This is a computational inference from projected DOS, not a direct transport-path measurement.

Temperature-dependent conductivity in Ag-BHT films is attributed to intergrain charge hopping between neighbouring nanocrystals and follows a 3D Mott variable-range hopping fit over 100-300 K.
Caveat: Authors state this behaviour reflects film electronic properties rather than intrinsic single-crystal transport; no bulk single crystal was obtained.
