摘要：

The neutral hexadentate Schiff base N-(1-pyridin-2-yl-phenylidene)-N'-[2-({2-[(1-pyridin-2-yl-phenylidene)amino]ethyl}amino)ethyl]ethane-1,2-diamine (L) was used to synthesize new lanthanide(III) complexes of type [M(L)(NCS)(3)](M = La, 1; Gd, 2; Tb, 3; Dy, 4). Single crystal X-ray diffractometry reveals the tricapped trigonal prismatic structure of all the compounds. Variable-temperature magnetic susceptibility measurements in 2-4 show the expected chi T-M versus T plot for an isolated, mononuclear lanthanide(III) ion with 4f(7), 4f(8), and 4f(9) configurations, respectively following Curie Law.
