Abstract
- We present the results of a multi-high-frequency single-crystal EPR study of a recently discovered triangular trinuclear Mn complex, [Mn 3 O(O 2 CMe) 3 (mpko) 3 ](ClO 4 ) · 3CH 2 Cl 2 . The obtained data set confirm the findings of earlier magnetic measurements, which suggested that this complex is a single-molecule magnet with a spin ground state of S = 6. The zero-field splitting parameters obtained from the present EPR study are: D = −0.3 cm −1 , B 4 0 = - 3 × 10 - 5 cm - 1 and g = 2.00. We also find a significant transverse anisotropy which can be parameterized by a rhombic distortion with an E value of at least 0.015 cm −1 .
