Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Because all conductivity measurements used ac techniques, the authors argue that interparticle contacts are less likely to dominate the conductivity data.
Caveat: The evidence is still from compressed-powder pellets; no single-crystal anisotropy measurements were possible.

The authors consider that similar rhodium systems, and possibly these coordination polymers, could be quenched one-dimensional metals or small-band-gap intrinsic/extrinsic semiconductors.
Caveat: This is an analogy to cationic rhodium tetrakis(monoisocyanide) systems, not a direct proof for the polymers.

Powder X-ray diffractometric trace analysis supports a stacked-layer structure with an extensive network of columnar metal chains.
Caveat: Detailed diffraction data are not reproduced in this paper; Rh-Rh distances are quoted from ref 4.
2076 · Introduction · Figure 1 · Linked to 4 structured results
The higher conductivity and lower resistivity of the 1,4-diisocyanobenzene polymer relative to the 4,4'-diisocyanobiphenyl polymer are attributed partly to its shorter Rh(I)-Rh(I) distance.
Caveat: Authors state that additional factors besides intermetallic interactions may control conductivity.

Orthogonal pi orbitals of the 1,4-diisocyanobenzene linkers are proposed to enable electronic-effect transfer within the two-dimensional layers of the polymer.
Caveat: Mechanistic interpretation; no single-crystal anisotropic measurements were available.

The rhodium(I) coordination polymers are electrically semiconductive at room temperature, with specific conductivities spanning 3.14 x 10^-6 to 1.65 x 10^-4 ohm^-1 cm^-1 in Table I.
Caveat: Measurements are on compressed powder pellets rather than single crystals.
