Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Antiferromagnetic interactions are observed for complexes 1 and 2 based on negative Weiss constants.
Caveat: Magnetic coupling pathways are discussed partly by analogy to literature.

High-nuclear 3d-4f Ln6Cu24 heterometallic clusters act as nodes for 3D supramolecular networks bridged by trans-Cu(amino acid)2 groups.
Caveat: Detailed selected bond lengths/angles are available in the supplied SI; full machine-readable CIF coordinates were not supplied locally.
3963-3964 · Abstract; Results and Discussion · Figure 1 · Linked to 4 structured results
The large conductivity difference between complex 1 and complex 2 is attributed to the packing mode of the Ln6Cu24 building blocks.
Caveat: The paper states this as a structural interpretation; no mechanistic transport model or activation energy is reported in the main text.

Replacing glycine with chiral L-proline changes the node-connection mode and gives a chiral face-centred-cubic framework for complex 2.
Caveat: The steric-effect explanation is author interpretation based on the two products; no systematic series is reported.
3966, 3968 · Results and Discussion; Conclusion · Figures 7, 8 · Linked to 2 structured results
Both 3D supramolecular polymers behave as semiconductors, with conductivity increasing as temperature rises.
Caveat: Conductivity was measured on ground-crystal pellets with unspecified atmosphere and no single-crystal anisotropy data.
