摘　　要：以HMFC[(反)-肉桂酰基二茂铁缩(S)-甲基二硫代碳酰腙]与HBFC[(反)-肉桂酰基二茂铁缩(S)-苄基二硫代碳酰腙]两种Schiff碱分别与醋酸镉[Cd(OAc)2?2H2O]、醋酸汞[Hg(OAc)2]反应,合成了6个未见文献报道的配合物Cd(MFC)2?H2O,Cd(MFC)OAc,Cd(BFC)2,Hg(MFC)2,Hg(MFC)OAc,Hg(BFC)2,考察了其物理性质,并利用元素分析、IR,1HNMR及摩尔电导表征了其组成、可能结构,推断了配位过程.结果表明:这两种Schiff碱都是反式双齿配体,经烯硫醇化并失去质子后,以负硫离子与过渡金属离子形成共价键,氮原子与中心金属离子形成配位键.Six complexes of two Schiff bases, methyl 1-ferrocenylcinnamylidene hydrazinodithiocarboxylate （HMFC） and benzyl 1-ferrocenylcinnamylidene hydrazinodithiocarboxylate （HBFC）, with M（OAc）2·nH2O [M=Cd（Ⅱ） or Hg（Ⅱ）, n=2, 0], Cd（MFC）2a·H20, Cd（MFC）OAc, Cd（BFC）2, Hg（MFC）2, Hg（MFC）OAc and Hg（BFC）2, hve been synthesized and characterized by elemental analysis, molar conductance, IR and ^1H NMR spectrum measurements. The possible coordinating process and complex structures have been discussed. It was found that two ligands are bidentate ones with trans configuration coordinating to the metal ions via nitrogens and sulfur atoms after their tautomerization of thione to thiol and deprotonation of the thiol.
