Redox Switching of Magnetic Anisotropy in Copper Verdazyl Complexes

Connie Chi published data on figshare in April 2026 detailing the synthesis and properties of copper(II) verdazyl complexes. The dataset includes high-field EPR measurements and DFT calculations for three redox states of the [Cu(dipyvd)2] species. It contains zero-field splitting parameters (D and E/D values) for the oxidized cations.

Use Cases

• Modeling magnetic anisotropy based on reported zero-field splitting parameters D and E/D.
• Correlating redox state with ground spin state (S = 1 or S = 3/2) as described in the study.
• Validating density functional theory (DFT) calculations against experimental EPR data.
• Analyzing the relationship between Jahn-Teller distortion and magnetic anisotropy axes.

Strengths

• Includes specific, quantitative zero-field splitting parameters (D = 4.5 cm–1, E/D = 0.04 for [Cu(dipyvd)2]+ and D = 1.5 cm–1, E/D = 0.3 for [Cu(dipyvd)2]2+).
• Data is associated with a peer-reviewed scientific synthesis and characterization process.
• Covers three distinct redox states of the same molecular core for comparative analysis.

Limitations

• Dataset is very small (4.3 KB), indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
