Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Concomitant polymorphism in Tm6(TTFTB)5 with an unidentified phase precluded bulk characterisation of the desired structure.
Caveat: This limits direct transfer of bulk transport/porosity/magnetic measurements to the Tm phase.
p004 · main text
Tm6(TTFTB)5 exhibits a novel (3,3,3,6,6)-coordinated 2D topology named lsx.
Caveat: Bulk Tm samples showed concomitant polymorphism, so bulk characterisation was not performed on phase-pure Tm material.

Yb6(TTFTB)5 and Lu6(TTFTB)5 are phase-pure and isostructural to Tm6(TTFTB)5 by PXRD.
Caveat: Isostructural assignment is based on PXRD comparison to simulated Tm pattern rather than separate single-crystal refinements for Yb/Lu.

Close intermolecular S...S contacts and TTF packing provide likely charge-transport pathways and indicate possible electronic delocalisation.
Caveat: The shortest S...S contacts are crystallographic metrics from the Tm structure; transport was measured on isostructural Yb/Lu analogues.

Activated Yb6(TTFTB)5 is microporous with BET area 400(1) cm2 g-1, whereas Lu6(TTFTB)5 gives only 70 cm2 g-1 under the same conditions.
Caveat: The lower Lu area is attributed to different stability despite structural similarity; the full Lu isotherm is not shown in the provided documents.

Bond lengths and temperature-independent paramagnetism suggest partial oxidation of TTFTB ligands and free charge carriers.
Caveat: The paper infers ligand radicals/partial oxidation from crystallographic metrics and magnetometry; no direct electrochemical measurement is reported.

The Yb and Lu TTFTB MOFs are electrically conductive pressed-pellet semiconducting MOFs, with average conductivities of 9(7) x 10^-7 and 3(2) x 10^-7 S cm-1, respectively.
Caveat: Measurements were on pressed pellets with two-contact geometry; authors note single-crystal studies may reveal higher anisotropic conductivities.
