Abstract

The crystallographic analysis of the title compound shows that there are two crystallographically independent molecules in a unit cell. The magnetic study clarified that every molecule behaved as a single-molecule magnet. Two series of the out-of-phase ac susceptibility signals appeared around 10 K even at zero dc field. The activation energies (Δ) for the magnetization reversal were estimated as Δ(1)/kB = 39.2(3) K with τ0(1) = 4.2(4) × 10−8 s and Δ(2)/kB = 36(2) K with τ0(2) = 4.1(12) × 10−7 s, where τ0 stands for the pre-exponential factor in the Arrhenius analysis. Magnetic hysteresis was recorded at 1.6 K by means of a pulsed-field technique. The role of exchange coupling is discussed.
