摘要

A series of heterometallic complexes of formula [Mn^IIILn ^III(bdeaH)₃(bdea)₂(piv)₈]-MeCN, where bdeaH₂= A/-butyldiethano-lamine, piv = pivalate, and Ln = Y (1), Tb (2), Dy (3), Ho (4), and Er (5), has been prepared. 1-5 are isostructural, with the metal centers forming a novel semicircular Ln"^l-Mn^l"-Ln^l"-Mn ^l"-Ln^l" strand. Only 2 and 3 exhibit slow relaxation of the magnetization, suggesting that the highly anisotropic Ln'" ions (Tb^ιπand Dy'") are essential for an energy barrier to spin reversal.
