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.
Compound 1 is a linear 1D polymer yet does not show the magnetic susceptibility maximum expected for previously known linear Ru2X chain compounds, implying weak antiferromagnetic interactions.
Caveat: Magnetic fit uses a model including zero-field splitting and paramagnetic impurity.
p006 · Magnetic properties · Linked to 2 structured results
The smaller Ru-X-Ru angle in the iodide derivative is invoked to explain its larger activation energy despite the shorter inter-dimer distance.
Caveat: Mechanistic interpretation from the authors rather than a directly measured band structure.
p005 · Electrical conductivity measurements · Linked to 2 structured results
Microwave activation gives single-phase microcrystalline powders, while solvothermal synthesis facilitates higher-quality single crystals for these insoluble products using ethanol or methanol solvents.
p002 · Synthetic aspects
Activation energies from Arrhenius plots increase in the order Cl < Br < I, approximately 1.4, 1.6 and 1.8 eV.
Caveat: Reported as approximate average values; individual crystal values were not tabulated.
p004 · Electrical conductivity measurements · Fig. 4 inset · Linked to 3 structured results
Compounds 7, 1 and 4 are semiconductors over 300-400 K, with 400 K conductivity increasing in the order Cl < Br < I.
Caveat: Conductivity values are ranges/averages across four or five crystals; room-temperature resistance exceeded the detection limit.
