Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and UO(2)(II) complexes with the ligand 2-tert-butylaminomethylpyridine-6-carboxylic acid methylester (HL(2)) have been prepared and characterized by elemental analyses, molar conductance, magnetic moment, thermal analysis and spectral data. 1:1 M:HL(2) complexes, with the general formula [M(HL(2))X(2)].nH(2)O (where M = Co(II) (X = Cl, n = 0), Ni(II) (X = Cl
Fe(III),Co(II),Ni(II),Cu(II),Zn(II)和UO(2)(II)与配体2-叔丁基氨基甲基吡啶-6-羧酸甲酯的络合物(HL( 2))已经准备好并通过元素分析,摩尔电导,磁矩,热分析和光谱数据表征。1:1 M:HL(2)配合物,通式为[M(HL(2))X(2)]。nH(2)O(其中M = Co(II)(X = Cl,n = 0 ),Ni(II)(X = Cl,n = 3),Cu(II)(灰色,X = AcO,n = 1),Cu(II)(黄色,X = Cl,n = 0)和Zn(II)(X = Br,n = 0)。此外,Fe(III)和UO(2)(II)配合物的类型为1:2 M:HL(2),其分子式为[Fe(制备了L(2))(2)] Cl和[UO(2)(HL(2))(2)](NO(3))(2),从IR数据可以看出HL(2 )配体表现为通过吡啶基N,羧基O和质子化NH基团与金属离子配位的三齿配体;
