Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The product is a continuous mixed-metal Schiff-base coordination polymer rather than a discrete complex.
Caveat: No crystallographic structure or powder diffraction evidence is reported; assignment relies on elemental analysis, spectroscopy, TG, and the proposed structure.
407 · 5. Conclusion · Figure 1 · Linked to 6 structured results
TG behaviour supports the proposed composition and absence of coordinated or lattice water.
Caveat: TG curve is low-resolution in the render, so decomposition details are taken from text rather than digitisation.

The pressed polymer pellet shows ohmic current-voltage behaviour and low activation energy semiconducting transport.
Caveat: Electrical geometry is two-electrode with silver-paint contacts; no uncertainty, replicate statistics, or single-crystal data are reported.

Hall and iodine-doping measurements indicate p-type behaviour, with iodine increasing conductivity as an electron-acceptor dopant.
Caveat: The Hall-sign value is not tabulated, and the iodine-doped fixed-field condition is inconsistently reported as 60 V/cm in text and 66 V/cm in the Figure 7 caption.
