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 2-Ln formulae are inferred from elemental analysis and TGA rather than crystallographic refinement.
Caveat: The molecular weight is described as roughly determined from elemental S content before comparing other elements and TG results.

2-Tb is the exception among the oxidised/magnetic series and is reported as not showing SMM behaviour under the tested 2 kOe dc field.
Caveat: Qualitative statement; no numeric result row was created for the absent signal.
14720 · Magnetic properties · Fig. S26
IR, PXRD and TGA evidence indicate that the framework topology is basically retained after iodine oxidation.
Caveat: The authors explicitly state that single-crystal structures of oxidised 2-Ln were not obtained.

The pristine frameworks retain redox-active TTF units that show two quasi-reversible one-electron redox processes.
Caveat: CV values are reported for 1-Ln; no analogous CV peak list is reported for 2-Ln.

Both 1-Dy and 2-Dy show field-induced single-molecule magnet behaviour under 1.5 kOe dc field.
Caveat: The paper also notes quantum tunnelling effects and double relaxation processes.

Iodine oxidation substantially increases the electronic conductivity of each Ln-MOF, with 2-Ln values in the 10^-7 to 10^-6 S cm^-1 range compared with 10^-10 to 10^-9 S cm^-1 for 1-Ln.
Caveat: Two-probe pressed-disc conductivities; no uncertainty or device dimensions are reported in the text.
