摘　　要：合成了O,O′-二乙基硫代磷酰肼与水杨醛、邻-香草醛缩合而成的席夫碱及其钼(Ⅵ)配合物,通过元素分析,IR,1HNMR,MS,UV-vis光谱,摩尔电导等对所合成的化合物进行了表征。谱学研究表明,配合物中金属钼离子为六配位,存在[Cis-MoO2]2+结构。另外,还对配合物进行了杀虫活性试验,试验结果表明配合物灭杀蚜虫的活性均高于甲胺磷,而它们灭杀红蜘蛛的活性均低于甲胺磷。Schiff bases of o,o＇-diethylphosphorohydrazono-thionate with salicylaldehyde（HSP） or 0-vanillin（HVP） and their Mo（Ⅵ） complexes had been synthesized.The synthesized compounds had been characterized by elemental analysis,IR,1HNMR,MS,UV / vis,and molar conductivity.The six-coordinate structure with [cis-MoO2]2＋ group in the complexes was proposed on the basis of spectroscopic characterization.The insecticidal activities of the Mo（Ⅵ） complexes to bollworm had also been investigated.The results indicated that the activities of the complexes in killing bug were more effective than those of methamidophos,are lower effective in killing red spider than those of methamidophos.
