通过联苯甲酰双缩肼(L)与不同金属乙酸盐[M(OAc)2]及2,3-二氯-5,6-二氰基对苯醌自由基离子(DDQ-·)反应,合成了3个分子式为(ML)2+(DDQ-·)2(M=Mn、Zn、Cd)的三元配合物及2个分子式为(ML)2+(DDQ-·)(OAc-)(M=Ni、Pb)的四元配合物.元素分析确定了它们的组成,经红外光谱、紫外-可见光谱及摩尔电导的测定对其配位情况进行了讨论.另将丁二酮双缩肼(L)与不同金属乙酸盐[M(OAc)2],及中性DDQ反应,合成了分子式分别为(ML)2+(DDQ-·)(OAc-)(M=Cu、Cd)、(ML)2+(DDQ)(OAc-)2(M=Co、Ni)及(HgL)2+(DDQ)1.5(OAc-)2的五个四元配合物.经元素分析、红外光谱、紫外-可见光谱,对它们进行了表征.固体电导的测定结果表明,含中性DDQ的配合物均属半导体范畴,其中Hg配合物的室温粉末固体电导率达3.7×10-4Ω-1cm-1. By the reaction of dibenzylidenehydrazide (L) with different metal acetate [M (OAc) 2] and 2,3-dichloro-5,6-dicyano-p-benzoquinone free radical ion , Three ternary complexes of (ML) 2+ (DDQ-) 2 (M = Mn, Zn, Cd) and two complexes of (ML) 2+ (DDQ- ·) (M = Ni, Pb) of the quaternary complex. Elemental analysis confirmed the composition of these compounds. The coordination of these compounds was investigated by FTIR, UV-Vis and molar conductance measurements. In addition, diacetyl bis (hydrazine) diacetate (L) was reacted with different metal acetate [M (OAc) 2] (OAc-) 2 (M = Co, Ni), and (HgL ") 2+ (DDQ) 1.5 Yuan complex. They were characterized by elemental analysis, IR and UV-Vis spectra. The results of solid conductivity measurements show that the complexes containing neutral DDQ belong to the semiconducting domain. The conductivity of Hg complexes at room temperature is 3.7 × 10-4Ω-1cm-1.
