CaveatSupport assessment: High
The authors caution that single-crystal MOF devices would be needed for more accurate quantification of through-bond and through-space transport pathways.

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
All six M-HHTP materials are highly crystalline and adopt a general honeycomb lattice, with metal-dependent stacking and coordination variations.
Caveat: Zn-HHTP is described as quasi-two-dimensional and lacks fully coplanar extended organic ligand layers.
main p.1-p.7, article p.311-p.317 · Summary/Results/Conclusions · Linked to 5 structured results
Structure Property LinkSupport assessment: High
Electrical conductivity in the M-HHTP series depends strongly on the identity, electronic configuration, and coordination geometry of the metal centre.

Transport MechanismSupport assessment: Medium
Mg-HHTP and Ca-HHTP likely conduct by through-space/spatial hopping dominated by organic ligands rather than through-bond pi-d conjugation.
Caveat: Mechanism is inferred from spectroscopy and calculations; authors state single-crystal devices would quantify through-bond versus through-space contributions more accurately.

Transport MechanismSupport assessment: High
Cu-HHTP has the highest 295 K pressed-pellet conductivity and the lowest activation energy/bandgap, attributed to planar tetragonal Cu coordination, mixed Cu2+/Cu+ states, and effective pi-d conjugation.
Caveat: Transport values are on pressed pellets and may include grain-boundary/contact effects; OPTP supports intrinsic short-range behaviour.

Transport MechanismSupport assessment: Medium
Transition-metal M-HHTP frameworks generally support through-bond charge transport through pi-d conjugation, with Zn-HHTP limited by filled d-shell/coordination geometry.
Caveat: Co and Ni show only moderate conductivity; Zn-HHTP is a transition-metal member but behaves poorly due to limited d-orbital contribution.
