Abstract O,O,N- or O,N-dichelating ligands, H4L1, H4L2, derived from new bis(hydroxybenzylidene)-substituted terephthalo and oxalo hydrazides were prepared and characterized by FT-IR and NMR spectroscopy (H4L1 = dicondensation of salicylaldehyde and terephthalic acid dihydrazide, H4L2 = dicondensation of salicylaldehyde and oxalic acid dihydrazide). [VO2}2(H2L1)] (1), [Cu(CH3OH)}2(L1)] (2), [Mn(CH3OH)}2(L1)]
摘要制备了由新的双(羟基亚苄基)取代的对苯二甲酰和草酰肼衍生的O,O,N-或O,N-螯合配体H4L1,H4L2,并通过FT-IR和NMR光谱进行了表征(H4L1 =水杨醛和水杨醛的缩聚反应)对苯二甲酸二酰肼,H4L2 =水杨醛和草酸二酰肼的缩聚反应。[VO2} 2(H2L1)](1),[Cu(CH3OH)} 2(L1)](2),[Mn(CH3OH)} 2(L1)](3)和[TiO(H3L1) [2](4)通过适当的金属盐与H4L1的反应合成了潜在的六齿的2 [ONO]供体配体[L1] 4-的配合物。配合物[VO(CH3O)(CH3OH)} 2(L2)](5),[Cu(CH3OH)} 2(L2)](6),[Mn(H2O)2(CH3OH)} 2( L2)](7)和[TiO(CH3OH)} 2(L2)]·2H2O(8)是通过相应的金属盐与H4L2反应合成的。所有复合物均通过显微分析
