Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Chemical oxidants give Cu3(HHTP)2 products matching expected PXRD, whereas no-oxidant air-free synthesis forms Cu2O and an unidentified secondary phase.
Caveat: PXRD peak broadening depends on drying history.

Increasing 2,5-dichloro-1,4-benzoquinone pre-oxidant decreases the length:diameter aspect ratio by over 60-fold, from rods to flakes.
Caveat: Samples are somewhat polydisperse.

Partial ligand oxidation before metal binding controls Cu3(HHTP)2 morphology, changing rods to blocks to flakes as pre-oxidant equivalents increase.
Caveat: Exact structure and role of oxidised HHTP polymer are not fully resolved.
p001; p005 · Abstract; Results and discussion · Figure 3 · Linked to 3 structured results
Commercial HHTP contains substantial NMR/EPR-silent impurity, and reagent purity strongly influences Cu3(HHTP)2 particle morphology.
Caveat: Impurity is attributed to oxidised polymeric/oligomeric HHTP but exact structure is unresolved.
p002 / article p.10473 · Ligand purity and synthetic reproducibility · Table S1 · Linked to 6 structured results
Morphology changes do not produce large conductivity changes; all Cu3(HHTP)2 materials are on the order of 10^-2 to 10^-3 S/cm.
Caveat: Pellet conductivities vary between replicates and depend on packing/contact geometry.
