Abstract

High-frequency/high-field electron paramagnetic resonance studies on two homonuclear 12-MC-4 metallacrown complexes Cu 4 Cu and Co 4 Co are presented. For Cu 4 Cu, our data imply axial-type g-anisotropy with g x =2.03±0.01, g y =2.04±0.01, and g z =2.23±0.01, yielding g=2.10±0.02. No significant zero field splitting (ZFS) of the ground state mode is observed. In Co 4 Co, we find a m S =±3/2 ground state with g=2.66. The data suggest large anisotropy D of negative sign.
