含硫希夫碱配合物的研究(Ⅳ)——邻羚基苯甲醛和β-萘酚醛与双硫代肼基甲酸酯衍生的希夫碱配合物

STUDIES OF COMPLEXES OF SCHIFF BASES CONTAINING SULFUR(Ⅳ)——Complexes of Thio-Schiff Bases Derived from S-Methyldithiocarbaze and o-Hydroxybenzaldehyde and o-Hydroxynaphthaldehyde

从 S—甲基双硫代肼基甲酸酯 H■_3S—■—NHNH_2与邻羟基苯甲醛和β—萘醛酚衍生出两种含硫希夫碱■=NNH■(HA)和■=NNHC■(HB),以这两种化合物为配体,合成了与锰,镍的四种新的螯合物。测定了它们的化学组成、溶液的电导、磁性、可见—紫外光谱、红外光谱以及顺磁共振谱等性质。实验结果表明,Ni(Ⅱ)与上述两种配体形成具有[NiL_2]形式的反磁性的平面正方形结构,而 Mn(Ⅱ)在形成配合物过程中转化为 Mn(Ⅲ),形成具有[MnL_2·OAC](式中 L^-为单价双齿阴离子配体,CAO^-为醋酸根)形式的四方锥结构。

Nickel anti manganese Complains of schiff bases,O-OHC_■H■CHNNHC(S) SCH_3(HA) and OOHC_(10)H_6CHNNHC(S)SCH_3(HB)havc been synthesized and Characterized by elemental analysis,molar conductivity,magnetic.susceptibility and Spectriscopic méasurements.The schiff bases HA and HB behave as[NS] bldentate Chelating agents forming 1:2 Complexes with nickel,which are dia- magnetic and Square-Plane Structures with formula [NiA_2]and [NiB_2]。The Schiff bases HA and HB react with Mn(OAC)_2 forming 5—Coordinatc Mn(Ⅲ)Complexes[MnA_2·OAC]and[MnB_2·OAC],which are Paramagnetic and square Pyramidal structures
