Ln-Pt Electron Polarization Effects on the Magnetic Relaxation of Heterometallic Ho- and Er-Pt Complexes

Abstract

Heterometallic Ln-Pt complexes with the formula [Ln2Pt3(H2O)2(SAc)12] (Ln = Ho(1), Er(2); SAc = thioacetate), were synthesized. From natural bond orbital (NBO), local orbital locator (LOL) analyses and X-ray absorption fine structure (XAFS) measurements, there was clear the Ln-Pt interactions or electron polarization. Butterfly-type hysteresis was observed for both 1 and 2. 1 and 2 underwent the field-induced slow magnetic relaxation up to 4 K. These magnetic properties were induced by Ln-Pt electron polarization.
