Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: Medium

Cu0.0Co1.0 has a high spin reversal barrier and is presented as promising for molecule-based spintronic devices.

Caveat: Application relevance is prospective; no device was fabricated in this paper.

6 · Discussion · Table 1 · Linked to 2 structured results

Phase AssignmentSupport assessment: High

Cu1.0Co0.0 is assigned as a narrow-band-gap diamagnetic semiconductor with Cu in the +1 oxidation state.

4 · Magnetic Interactions Crossover · Figures 3, S7, S9 · Linked to 4 structured results

Phase AssignmentSupport assessment: High

The series crosses from ferromagnetic insulators at Cu < 50%, to a paramagnetic semiconductor at Cu = 50%, to antiferromagnetic semiconductors at Cu > 50%.

Caveat: High-Cu exchange constants are described by the authors as rough estimates because the full spin Hamiltonian was too complex.

5 · Magnetic Interactions Crossover · Figure 4b · Linked to 6 structured results

Structure Property LinkSupport assessment: High

Cu doping changes electronic and magnetic properties while retaining the same overall crystal structure by PXRD.

Caveat: Full crystallographic CIF was not provided in the local document set; CCDC deposition is queued as low priority.

2 · Synthesis of the 1D Coordination Polymers · Figure 1b; Table S3 · Linked to 3 structured results

Transport MechanismSupport assessment: High

Cu doping produces a continuous electronic crossover from insulating to semiconducting states in the 1D coordination-polymer series.

Caveat: Conductivity values for some intermediate compositions are estimated from Figure 3a rather than tabulated.
