【摘要】 通过含新结构单元钴化合物:Co_3(bdt)_3(PBu_3)_3(Ⅰ),Co_3(tdt)_3(PBu_3)_3(Ⅱ),[Co_3(bdt)_3(PPh_3)_3][CoBr_3(dmf)](Ⅲ)和[Co_3(edt)_3(PEt_B)_3]_2[Co_2Cl_4(Et_2SO_2)_2](Ⅳ)(bdt=1,2-S_2C_6tdt=4-Me-1,2-S_2C_6,edt=SCH_2CH_2S ̄(2-))的磁极矩和 ̄1HNMR等研究表明:它们均具顺磁性,钴原子之间存在着反铁磁偶合作用,同时还讨论了它们的磁学性质和分子结构之间关系。

【Abstract】 Four cobalt compounds containing a novel structural unit [Co3(SS)3(PR33]:Co3(bdt)3(PBu33(Ⅰ), Co3(tdt)3(PBu33(Ⅱ),[Co3(bdt)3(PPh33][CoBrt(dmf)](Ⅲ) and [Co3(edt)3(PEt33]2 [Co2Cl4 (Et2SO22](Ⅳ)(bdt=1,2-S2C6H,tdt=4-Me-1,2-S2C6 ,edt=SCH2CH2S2- were studied by means of magnetic susceptibllity and 1H NMR. The results indicate that they are paramagnetic compounds with antiferromagneticcoupling among the paramagnetic metal co balt atoms. Herein the relation betweentheir magnetic characteriZation and molecular structure is discussed.
