High-frequency EPR study on Cu4Cu- and Co4Co-metallacrown complexes
High-frequency/high-field electron paramagnetic resonance studies on two homonuclear 12-MC-4 metallacrown complexes Cu4Cuand Co4Coare presented. For Cu4Cu, our data imply axial-type g-anisotropy with gx=2.03±0.01, gy=2.04±0.01, and gz=2.23±0.01, yielding g=2.10±0.02. No significant zero field splitt...

| Zusammenfassung: | High-frequency/high-field electron paramagnetic resonance studies on two homonuclear 12-MC-4 metallacrown complexes Cu4Cuand Co4Coare presented. For Cu4Cu, our data imply axial-type g-anisotropy with gx=2.03±0.01, gy=2.04±0.01, and gz=2.23±0.01, yielding g=2.10±0.02. No significant zero field splitting (ZFS) of the ground state mode is observed. In Co4Co, we find a mS=±3/2 ground state with g=2.66. The data suggest large anisotropy D of negative sign. |
