Compounds 1 and 2 are isostructural/isotypical 1D Zn(II) coordination polymers with chair-like hexagonal [Zn6(mu3-OH)4]8+ SBUs.
Caveat: Supported by main text, SI Table S1 and CIF files; selected bond tables are not exhaustively enumerated in this extraction.
13971-13973 · Abstract; Results and discussion · Fig. 1 · Linked to 8 structured results
Freshly prepared samples of compounds 1 and 2 are reported as phase pure by PXRD comparison with simulated single-crystal patterns.
Caveat: PXRD traces were checked in rendered SI pages; no raw peak list was provided.

The compound 1 device outperforms compound 2 in conductivity, Schottky barrier height, series resistance, SCLC conductivity, mobility, carrier concentration and mobility-lifetime product.
Caveat: Compound 2 has a lower ideality factor and slightly longer carrier lifetime; authors nevertheless judge compound 1 superior overall.
13975-13976 · Electrical characterisation; Conclusions · Table 1; Table 2 · Linked to 14 structured results
The higher conductivity of compound 1 is attributed to its shorter interchain {Zn6}-cluster centre distance relative to compound 2.
Caveat: This is the authors' structure-property attribution based on a two-compound comparison; Fig. S3 and Table S1 support the shorter adjacent-chain distance for compound 1.
13974; 13976 · Electrical characterisation; Conclusions · Linked to 6 structured results
Changing the para substituent on the benzoate ligand from chloro to bromo alters interchain interactions and modifies electrical conductivity and Schottky behaviour.
Caveat: Only two related compounds are compared; no independent variable series beyond Cl and Br is presented.
13971; 13976 · Abstract; Conclusions · Linked to 6 structured results
Both Zn(II) coordination polymers show non-linear rectifying J-V behaviour consistent with Schottky diode behaviour.
Caveat: The exact J-V curves are graphical; diode parameters are tabulated.
13974 · Electrical characterisation · Fig. 5a · Linked to 4 structured results
The devices exhibit Ohmic behaviour at low bias and SCLC-dominated transport at higher forward bias.
Caveat: The slope analysis is described textually and shown in Fig. 5d; raw fit slopes are not tabulated.
