Synthesis, spectroscopic and thermal studies of some complexes of a new N(2)-Schiff base ligand of N(1),N(2)-bis((E)-2-methyl-3-phenylallylidene)ethane-1,2-diamine (L) with a general formula of MLX(2) (M = Zn(II), Cd(II) and Hg(II); X = Cl(-), Br(-), I(-), SCN(-) and N(3)(-)) are described. The ligand and its complexes were characterized by elemental analysis, molar conductance, UV-vis spectra, FT-IR spectra, MS, (1)H NMR and (13)C NMR spectra. The conductivity measurement as well as spectral data indicated that the complexes are non-electrolyte. (1)H and (13)C NMR spectra have been studied in DMSO-d(6) and/or CDCl(3). The thermal behavior of the complexes shows weight loss by decomposition of the anions and ligand segments in the subsequent steps. Activation thermodynamic parameters of decomposition such as E*, ΔH*, ΔS* and ΔG* were calculated from TG curves.
合成、光谱和热研究一些配合物的新型 N(2)-席夫碱配体的 N(1),N(2)-双((E)-2-甲基-3-苯基丙烯亚基)乙二胺 (L) 与一般式 MLX(2) (M = Zn(II), Cd(II) 和 Hg(II); X = Cl(-), Br(-), I(-), SCN(-) 和 N(3)(-))。配体及其配合物的特征元素分析、摩尔电导率、紫外可见光谱、FT-IR 光谱、MS、(1)H NMR 和 (13)C NMR 光谱。电导率测量以及光谱数据表明,这些配合物是非电解质。(1)H 和 (13)C NMR 光谱在 DMSO-d(6) 和/或 CDCl(3)中进行了研究。配合物的热行为表明,在随后的步骤中,通过阴离子和配体片段的分解会发生重量损失。从 TG 曲线计算了分解的活化热力学参数,如 E*、ΔH*、ΔS和 ΔG。
