摘要：
Structures and magnetic characteristics of two three-coordinate erbium(III) compounds with C-3v geometry, tris(2,6-di-tert-butyl-pcresolate) erbium, Er(dbpc)(3) (1) and tris(bis(trimethylsilyl) methyl) erbium, Er(btmsm)(3) (2), were determined. Both underwent temperature- dependent slow magnetic relaxation processes in the absence of an external magnetic field. As a result of the differences in the coordination environment, they exhibit different energy barriers and quantum tunneling of magnetization (QTM) constants.
