New complexes of Co(II), Ni(II), Cu(II) and Zn(II) with four new tetraaza Schiff base ligands, N,N′-bis(2-quinolylmethylidene)-1,2-ethanediimino (L1), N,N′-bis(2-quinolylmethylidene)-1,2-propanediimino (L2), N,N′-bis(2-quinolylmethylidene)-1,3-propanediimino (L3), N,N′-bis(2-quinolylmethylidene)-4-nitro-1,2-phenylenediimine (L4), were synthesized and characterized by elemental analysis, IR, 1H NMR
Co(II),Ni(II),Cu(II)和Zn(II)与四个新的四氮杂席夫碱配体N,N'-双(2-喹啉基亚甲基)-1,2-乙烷二亚氨基(L 1),N,N′-双(2-喹啉基亚甲基)-1,2-丙二胺(L 2),N,N′-双(2-喹啉基亚甲基)-1,3-丙二胺(L 3),N,N′合成了-双(2-喹啉基亚甲基)-4-硝基-1,2-苯二胺(L 4),并通过元素分析,IR,1 H NMR和UV-Vis光谱进行了表征。在恒定的离子强度为0.1 M(NaClO 4),在25°C下的MeOH溶剂中。发现给定金属离子与配体的络合物形成趋势如下L 2 > L 1 > L 3 > L 4,给定配体与金属离子的趋势为Co(II)> Ni( II)> Cu(II)> Zn(II)。
