and its five complexes [NiL2], [CuL2], [ZnHL(H2O)2(OAc)2], [CdHL(H2O)2(OAc)2]·2H2O and [MnHL(H2O)2(OAc)2]·2H2O were synthesized. The ligand and metal complexes were characterized by spectroscopic methods (FT-IR, 1H and 13C NMR, UV–Vis), elemental analyses, mass spectrometry, and conductance measurements. Of these complexes, [NiL2] was structurally characterized by single-crystal X-ray crystallography
摘要 硫醚不对称 N2S 供体席夫碱配体 N-2-((2-nitrophenyl)thio)phenyl)-1-(pyrrole-2-yl)methanimine (HL) 及其五种配合物 [NiL2]、[CuL2]、合成了[ZnHL(H2O)2(OAc)2]、[CdHL(H2O)2(OAc)2]·2H2O和[MnHL(H2O)2(OAc)2]·2H2O。配体和金属配合物通过光谱方法(FT-IR、1H 和 13C NMR、UV-Vis)、元素分析、质谱和电导测量表征。在这些配合物中,[NiL2] 的结构特征是单晶 X 射线晶体学。在该复合物中,两个配体作为一元 N2S 三齿并通过吡咯-N、硫醚-S 和偶氮甲碱-N 配位,而镍 (II) 处于扭曲的八面体环境中。图形概要
