本文报道了4-犤(N-甲基-N-羟乙基)氨基犦苯甲醛缩氨基硫脲(HL)及其金属配合物的合成,通过元素分析、红外光谱、紫外、核磁共振对配体和配合物进行了表征。配合物的组成为ML2(M=Ni?、Cu?、Zn?、Cd?、Pd?)。晶体结构分析表明配体分子中除了羟乙基偏离平面外,其余各原子几乎在一个平面上。晶体结构中存在N-H…O(N1…O1)和O-H…S氢键,形成一个二维网状结构。在与金属离子配合时,配体由硫酮式转变为硫醇式作为负一价二齿配体通过S和β-N与金属离子螯合,形成稳定的中性配合物。
In this paper, the synthesis of 4-azulene (N-methyl-N-hydroxyethyl) aminobenzaldehyde thiosemicarbazone (HL) and its metal complexes was reported. The results of elemental analysis, IR, UV and NMR Body and complexes were characterized. The composition of the complex is ML2 (M = Ni ?, Cu ?, Zn ?, Cd ?, Pd?). Crystal structure analysis shows that in addition to the hydroxyethyl monomer off the plane, the rest of the atoms in almost a plane. There are N-H ... O (N1 ... O1) and O-H ... S hydrogen bonds in the crystal structure to form a two-dimensional network structure. When complexed with a metal ion, the ligand transitions from a thioketone to a thiol, which acts as a negative monovalent bidentate ligand to chelate the metal ion via S and β-N to form a stable, neutral complex.
