Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CP 1 is a phase-pure 2D Cd coordination polymer with sql topology and five lattice waters in the crystal lattice.
Caveat: Bulk phase purity is based on qualitative PXRD matching to simulated data.

CP 1 is reported to have better electronic-device performance than CP 2, with higher conductivity, higher rectification ratio, and higher effective carrier mobility.
Caveat: The authors attribute the difference to Cd(II) size and a 2D interdigitated network with greater pi-pi interactions; this is a structure-property interpretation rather than a separately isolated variable.
7531 · Conclusions · Linked to 6 structured results
The charge-conduction mechanism is divided into an ohmic low-voltage region and a higher-voltage SCLC-like region.
Caveat: Slope values were read from the plotted figure labels and are approximate; the region assignment is the authors' interpretation.
7529 · Electrical studies · Figure 7 · Linked to 4 structured results
Both CP 1 and CP 2 exhibit semiconducting electrical conductivity and Schottky barrier diode behaviour in Al/compound/ITO devices.
Caveat: Transport was measured on spin-coated device films; no single-crystal conductivity tensor is reported.
