New metal chelates of ZnII and CdII (ML2) based on (4Z)-3-methyl-1- phenyl-5-thioxo-1,5-dihydro-4-H-pyrazol-4-one quinolin-8-ylhydrazone (HL1) and (4Z)-5- methyl-2-phenyl-4-[(quinolin-8-ylimino)methyl]-2,4-dihydro-3H-pyrazole-3-thione (HL2) were synthesized. The structures of the metal chelates were studied by EXAFS and NMR (1H, 13C, and 111Cd) spectroscopy. The structure of the Cd(L1)2 complex was established by X-ray diffraction analysis. The complexes have pseudooctahedral structures with the N4S2 ligand environment.
基于 (4Z)-3-甲基-1-苯基-5-硫代-1,5-二氢-4-H-吡唑-4-酮喹啉-8-基腙 (HL1) 的新型 ZnII 和 CdII 金属螯合物 (ML2) )和(4Z)-5-甲基-2-苯基-4-[(喹啉-8-亚氨基)甲基]-2,4-二氢-3H-吡唑-3-硫酮(HL2)被合成。通过 EXAFS 和 NMR(1H、13C 和 111Cd)光谱研究了金属螯合物的结构。通过X射线衍射分析确定了Cd(L1)2配合物的结构。该配合物具有 N4S2 配体环境的假八面体结构。
