Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Phase AssignmentSupport assessment: High

PXRD and elemental analysis support that the as-isolated bulk samples of compounds 1 and 2 are phase pure.

Caveat: PXRD evidence is reported in SI Fig. S3; numerical diffractogram data were not available.

4 · 3.4 Bulky purity and magnetic properties · Fig. S3 · Linked to 2 structured results

Structure Property LinkSupport assessment: High

Compound 1 is essentially paramagnetic whereas compound 2 shows weak antiferromagnetic coupling, consistent with the more compact network in compound 2.

6 · 3.4 Bulky purity and magnetic properties · Linked to 4 structured results

Structure Property LinkSupport assessment: Medium

Different C-H...Cl hydrogen-bonding patterns of bpy versus phen are proposed to drive the structural differences between compounds 1 and 2.

Caveat: The paper presents this as a structural interpretation, not a controlled mechanistic proof.

7 · 4. Conclusion · Linked to 2 structured results

Transport MechanismSupport assessment: High

Both coordination polymers behave as semiconductors by impedance spectroscopy, and compound 2 is more conducting than compound 1.

Caveat: Conductivity was inferred from impedance arcs and fitted resistances; no direct conductivity value was reported.
