摘要：

A new chiral mononuclear Dy(III) complex, [Dy((-)-pbipy)(pdtc)(3)] (1) (pbipy = 4,5-pinene-2,2'-bipyridine, pdtc = pyrrolidine-dithiocarbamate) has been synthesized and structurally characterized. Magnetic studies show that complex 1 exhibits field-induced single-ion magnet behavior with tau(0) = 4.2 x 10 (7) s and U-eff/k = 56.7 K, which is the first example of homochiral complex derived from S-donor pyrrolidine-dithiocarboxylate with slow magnetic relaxation.
