摘　　要：将新制的金刚烷胺缩邻香草醛Schiff碱(以下简称Schiff碱)与溶有等摩尔NaOH的甲醇溶液混合后,再滴入同等摩尔六水合氯化镍,回流6h,即得四核镍(Ⅱ)簇合物(以下简称簇合物).簇合物分子组成为[Ni_4L_4(μ3-OMe)4(MeOH)_4](L为去质子邻香草醛).用元素分析、红外光谱和X射线单晶衍射等手段对簇合物进行了表征.在外场1000Oe,温度范围2~300K的条件下测试了簇合物的变温磁化率.计算得到其居里常数为5.68cm^3Kmol^(-1),外斯常数为12.98K,表明簇合物中顺磁离子之间存在铁磁相互作用.The newly Schiff base, which derived from adamantaneamine and O-vanillin, was mixed with equimolar NaOH in methanol under stirring for 10 minutes. Equimolar nickel chloride hexahydrate in methanol was added dropwise into this resulting mixture. A tetranuclear nickel （ Ⅱ ） cluster was obtained after reflux for 6 h. The composition of the cluster is E Ni4L4 （ tx3 - OMe）4 （MeOH） 4 ] （ L being deprotonated O-vaniliin）. It was characterized by elemental analysis, IR and X-ray single crystal diffraction. The variable-temperature magnetic susceptibility of the cluster was measured under an applied field of 1 000 Oe at temperature ranging from 2 to 300 K. The Curie constant was calculated as 5.68 cm3 K mo1-1 and Weiss constant as 12.98 K,which was indicativeof ferromagnetic exchange between the paramagnetic ion.
