Magnetic Anisotropy in Homoleptic [CoX4]2– Complexes: Spectroscopic and Ligand Field Data

Adiat A. Fakolujo presents spectroscopic and magnetic data for the homoleptic tetrahedral cobalt complexes (NEt4)2[CoX4] (X = Cl, Br, I). The dataset includes results from single-crystal X-ray diffraction, DC/AC magnetic susceptibility measurements, inelastic neutron scattering, far-infrared magneto-spectroscopy, and high-frequency electron paramagnetic resonance. The work explores how geometric distortion from perfect tetrahedral symmetry influences magnetic anisotropy and spin relaxation behavior across the series.

Use Cases

• Modeling magnetic anisotropy based on spectroscopic data mentioned in the description
• Correlating crystallographic symmetry with magnetic properties based on the described D2d symmetry distortions
• Investigating spin-phonon couplings using far-infrared magneto-spectroscopy data
• Applying ligand field theory calculations to analyze trends in spin-orbit coupling

Strengths

• Data includes results from multiple advanced spectroscopic techniques (X-ray diffraction, INS, FIRMS, HFEPR)
• Covers a well-defined series of three homoleptic complexes (Co-Cl, Co-Br, Co-I) for comparative study
• File size is 7.6 MB, indicating a focused dataset with specific experimental results

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
