摘要

The synthesis, X-ray crystal structure and magnetic properties of a new dodecanuclear manganese complex [Mn12O12(O2CCH2Br) 16(H2O)4] - 4CH2Cl2(2) - 4CH2Cl2 are reported. Complex 2 · 4CH2Cl2 crystallizes in tetragonal space group I41/a with the following cell dimensions at 293(2) K: a = b = 26.697(4) Å, c = 13.246(4) Å, and Z = 4. The results of DC and AC magnetic susceptibility studies are described. DC measurements show the presence of hysteresis loops, and the out-of-phase component of AC magnetic susceptibilities has a frequency dependent maximum. Step-like features are seen on hysteresis loops and quantum mechanical tunneling could be the origin of these unusual relaxations.
