资源简介：
Three new single paramagnetic lanthanide-based
complexes, [Ln(L)(LOEt)] (Ln3+ = Dy3+, Tb3+, and Ho3+), are synthesized with the
multidentate calix[4]arene ligand H2L (H2L =
5,11,17,23-tetrakis(1,1-dimethylethyl)-25,27-dihydroxy-26,28-dimethoxycalix[4]arene)
and Kläui’s tripodal ligand LOEt– (LOEt– = (η5-cyclopentadienyl)tris(diethylphosphito-p)cobaltate(III)). All of the complexes have been characterized
by single crystal X-ray diffraction analysis, thermal stability, absorption
spectra, and magnetization measurements. The magnetic properties and
magnetostructural correlation in this seven-coordinated system are
investigated. The dysprosium complex 1 shows typical
single-molecule magnetic behavior with characteristic magnetic hysteresis
loops and the slow relaxation of magnetization.
