Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The formula is charge-balanced by Mn(+II), Na+, six monoanionic [bipy]- ligands and five neutral bipy ligands in interpenetrating cationic and anionic chains.
Caveat: C-C distances are described as indications, with XANES used to confirm Mn oxidation state.
4 · [Na2Mn2(4,4'-bipy)7(2,2'-bipy)4] Coordination Polymer · Figure 5 · Linked to 3 structured results
The Mn(0)-nanoparticle redox approach allows formation of a Mn-coordinated interpenetrating bipyridyl network and may enable other semiconducting or metallic bipyridyl coordination polymers.
Caveat: Generality beyond this manganese compound is proposed, not demonstrated in this paper.
1 · Abstract · Linked to 3 structured results
Compound 1 is a semiconductor with silicon-comparable conductivity, positive temperature gradient and optical band gap below 1.5 eV.
Caveat: Conductivity was measured on pressed pellets and the paper notes contact resistance; mechanistic verification is deferred to follow-up studies.
5-6 · Optical Properties and Electrical Conductivity; Conclusions · Figure 7 · Linked to 4 structured results
Electron transport is proposed to occur most probably through the Mn-bipyridyl chains via half-occupied Mn2+ 3d orbitals and neighbouring anionic bipyridyl ligands.
Caveat: The authors explicitly state that the conductivity mechanism must be verified in follow-up studies.
