Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The pristine two-dimensional Mn-pyrazine-chloride coordination polymer exhibits semiconducting electrical behaviour.
Caveat: Conductivity calculation depends on pellet thickness and area, which are not reported.
269-270 · Abstract; conductivity discussion · Fig. 3 · Linked to 3 structured results
The polymer framework is thermally robust in air up to about 310 C.
Caveat: The main-text stability threshold is explicit; additional Fig. S1 curve values are visual estimates from the rendered SI plot.

The crystallographic validation report contains level A alerts, including an ADDSYM suggestion of possible C2/m pseudo/new symmetry.
Caveat: The checkCIF report also states that structure factors were not supplied, so the full set of tests could not be run.
1-2 · checkCIF/PLATON report · Linked to 2 structured results
The coordination polymer is assigned as a triclinic P-1 two-dimensional rectangular framework with an infinite sheet structure.
Caveat: checkCIF flags possible higher/pseudo symmetry C2/m and several validation alerts.
270 · Structural discussion · Fig. 1 · Linked to 5 structured results
The authors attribute conductivity to electron transfer through compact columnar aromatic pi-pi interactions and pi/metal transfer pathways.
Caveat: Mechanism is proposed from structure-property correlation rather than direct electronic-structure or spectroscopic proof.
