Author interpretations and caveats

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

Application RelevanceSupport assessment: Medium

Complex 1 shows the strongest blue solid-state emission among complexes 1-4 and is suggested as potentially useful for functional materials.

Caveat: Application relevance is speculative; no device or performance testing is reported.

CaveatSupport assessment: High

The only electrical-transport-like measurement is molar electrical conductivity of aqueous solutions of 5 and 6; no solid-state electronic conductivity, thermoelectric, device, electrochemical or gas-sorption measurements are reported for the frameworks.

Caveat: Conductivity reflects dissociated solution species, not framework charge transport.

Phase AssignmentSupport assessment: Medium

PXRD comparisons indicate the bulk synthesised materials and as-grown single crystals are homogeneous for complexes 1-6, despite minor unindexed or broadened lines.

Caveat: XRPD patterns are shown graphically in SI Fig. S8; the text acknowledges a few un-indexed diffraction lines and slight broadening.

Structure Property LinkSupport assessment: High

ESI-MS and molar conductivity support dissociation of the original polymeric structures of 5 and 6 into ionic species in water.

Caveat: The species assignments are based on ESI-MS and conductivity rather than direct structural measurement in solution.

Synthesis MechanismSupport assessment: High

Different alkali-metal ions regulate the assembly of Cd/Zn perhalogenated terephthalate coordination polymers, producing different 1D/3D architectures.

Caveat: Mechanistic conclusion is based on comparative products under related room-temperature evaporation conditions.
