have been prepared. The structures of the polymer complexes were elucidated using elemental analysis, 1H NMR, UV–Vis, IR spectroscopies, magnetic moment, molar conductance and thermal analysis. The polymer complexes were isolated in 1:1 and 1:2 (M:L) ratios. The solid monocomplexes (1:1) (M:L) were isolated in the general formula [Fe(HL)O2SO2(OH2)2]. The biscomplexes (1:2) (M:L) solid chelates found
摘要 制备了对丙烯酰胺基硫胍 (HL) 与 Ni(II)、Fe(II) 和 Pd(II) 盐的聚合物配合物。使用元素分析、1H NMR、UV-Vis、IR 光谱、磁矩、摩尔电导和热分析阐明了聚合物配合物的结构。聚合物复合物以 1:1 和 1:2 (M:L) 的比例分离。固体单络合物 (1:1) (M:L) 以通式 [Fe(HL)O2SO2(OH2)2] 分离。发现双络合物 (1:2) (M:L) 固体螯合物具有通式 [Ni(HL)2X2]n (X = Cl−, Br−, I−, NO 3 - , NCS−), [Fe (HL)(en)(OSO3)(OH2)]n 和 [Ni(HL)2(Py)2]nX2,而 [Pd(L)X]2}n (1:1) (X = Cl−或 Br-)。在所有聚合物配合物中,发现配体和阴离子与 Ni(II) 和 Fe(II) 离子配位。从红外光谱可以明显看出配体的双齿性质
