Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu5BHT crystals exhibit chemical and thermal stability under the tested solvent exposure and nitrogen annealing conditions.
Caveat: Stability evidence is qualitative TEM/SAED retention after specific treatments, not a broad degradation study.

Spectroscopy assigns Cu in Cu5BHT primarily to +1 Cu-S coordination with no detectable Cu2+ species.
Caveat: XPS detected oxygen is assigned by the authors to extrinsic adsorbed water or oxygen-containing ambient species.

Cu5BHT is a low-symmetry conductive coordination polymer with an asymmetric kagome-like lattice built from square-planar CuS4 and non-planar Cu2S4 SBUs.
Caveat: Experimental long-range P2gg assignment differs from the local P1 DFT-optimised structure, which the SI attributes to configurational averaging.

In-plane electrical anisotropy is attributed to conductive 1D CuS4 chains along (010) linked by less conductive Cu2S4 slabs/blocks.
Caveat: Device-to-device/figure-vs-text conductance magnitudes are not fully reconciled in the paper; the anisotropic ordering is consistent.
p006 / article page 6 of 7 · Conclusion · Figures 3, 4, S26 · Linked to 5 structured results
The authors propose Cu5BHT forms through thiol coordination to Cu2+, electron transfer to Cu+, and subsequent Cu+-thiol or (Cu+)2 cluster-thiol complex formation.
Caveat: Mechanism is reasoned from spectroscopy and schematic Figure S9 rather than direct observation of intermediates.

Cu5BHT behaves as a metal in single-crystal transport, with conductance increasing on cooling along all measured in-plane crystal directions.
Caveat: The polycrystalline/thick-film van der Pauw measurement instead decreases in conductivity upon cooling, which the authors attribute to inter-grain hopping.
