2，6─二甲酸─4─取代苯酚双缩苯甲酰肼双核铜（Ⅱ）配合物的合成与磁性

SYNTHESIS AND MAGNETIC PROPERTIES OF BINUCLEAR COPPER COMPLEXES$WITH 2,6-DIFORMYL-4-SUBSTITUDEDPHENO DI(BENZOYLHYDRAZONE)

本文合成并表征了两个新的双核铜（Ⅱ）配合物：〔Ｃｕ２（Ｌ）（μ─Ｃｌ）Ｃｌ２〕，配体Ｌ为２，６─二甲酰─４─甲基苯酚双缩苯甲酰肼，取代基分别为氯（Ｌ１）和叔丁基（Ｌ２）．配合物具有相同的组成和配位构型．变温磁化率（４－３００Ｋ）测定结果表明，由于取代基不同，其磁交换参数分别为－４６．２ｃｍ（－１）（Ｌ１）和－５７．６ｃｍ（－１）（Ｌ２）．

Two binuclcar copper complexes(Cu2(L)(μ-Cl)Cl2) have been synthesized and characterized The ligand L denotes,2,6-diformyl-4-substitudedphenol di(benzoylhydrazone),where the substituent are chloride(L1)and tert-butyl(L2),respectively. The complexes have the same constitution and coordination environment.The determination of variable-temperature magnetic suseeptibilities indicates that the magnetic exchanges parmeters are -46.2cm(-1)(L1)and -57.6cm(-1)(L2), respectively.
