| STUDY ON SOME BIS-SCHIFF BASES FROM ISOPHTHALIC ALDEHYDE AND THEIR COPPER(Ⅱ) COMPLEXES |

| 摘要: 用2-甲氧基-5-氯-1,3-苯二甲醛与含有不同取代基团X的邻氨基酚缩合,合成了一系列双Schiff碱L-X(X=OMe,diMe,Me,t-Bu,H,Cl,NO2),它们与乙酸铜(Ⅱ)作用生成了一系列的双核配合物Cu2L-X(OEt).用红外、紫外、磁天平、顺磁共振等手段对配合物进行了表征,并通过量化计算(CNDO/2法)探讨了配合物的成键性质。研究结果表明,该类配合物是一个较大的共轭体系,配合物中Cu(Ⅱ).Cu(Ⅱ)之间有较强的反铁磁性交换作用,其共轭程度和交换作用强弱皆随X基团的不同而呈现某种变化规律。 |

| Abstract: From 2-methoxy-5-chloro-isophthalic aldehyde and 2-amino-4 (or 6) -X-phenol (X=OMe,diMe,Me,t-Bu,H,Cl,NO2) were synthesized a series of bis-Schiff bases(L-X),which formed a series of binuclear copper(Ⅱ) complexes(Cu2 L-X(OEt)).The complexes were characterized by IR,UV-Vis,Magnetic Susceptibility and ESR.The nature of the bonding of copper (Ⅱ) were discussed by CNDO/2 method of quantum chemistry.The result suggested that the complexes are large conjugated systems and there is a strong antiferromagnetic exchange interaction between copper(Ⅱ) and copper(Ⅱ),the properties of conjugation and interaction are influenced differently by altering X group. |
