Abstract:
An oxo-centered [Cr3O(O2C(t)Bu)6(H2O)3](O2C(t)Bu) HO2C(t)Bu·2EtOH triangular cluster has been synthesized and its magnetic properties have been studied by means of complementary techniques, namely magnetometry, specific heat and multi-frequency Electron Paramagnetic Resonance (EPR). Measurements on oriented single-crystals evidenced the presence of anisotropy that we attributed to the combined effect of Dzyaloshinskii-Moriya exchange interaction and distortion. By means of a minimal set of parameters, we show that a simple analytical model well describes the main features of the full set of experimental data.
