Abstract

An air-stable dysprosium(iii) complex, [C(NH₂)₃]₄[DyF(piv)₄](piv)₂(piv = pivalate), with a terminal fluoride ligand protected by forming extensive hydrogen bonds with peripheral guanidiniums has been isolated. Though the magnetic data failed to determine the energy barrier for the magnetic reversal (U_eff) accurately, the fine emission spectrum of the⁴F_9/2?⁶H_15/2transition at 4.2 K andab initiocalculations reveal that theU_effis about 376(20) K, which is among the highest for high-coordinate (coordination numbers = 9) lanthanide mononuclear magnets.
