A series of metal complexes of Zn(II) and Hg(II) having the general composition [M(L)(2)]X(2) [where L = 2-formylpyridine thiosemicarbazone; M = Zn(II) and Hg(II); X = Cl(-), NO(3) (-) and 1/2SO(4) (2-)] have been prepared and characterized by elemental chemical analysis, molar conductance, and spectral (IR and mass) studies. The IR spectral data suggests the involvement of sulphur and azomethane nitrogen in coordination to the central metal ion. On the basis of spectral studies, a tetrahedral geometry has been assigned for Zn(II) and Hg(II) complexes. The free ligand and its metal complexes have been tested in vitro against a number of microorganisms in order to assess their antimicrobial properties.
一系列的锌(II)和汞(II)金属配合物具有一般组成[M(L)(2)]X(2)[其中 L = 2-甲酰基吡啶缩氨硫脲; M = Zn(II)和 Hg(II); X = Cl(-),NO(3)(-)和 1/2SO(4)(2-)]已经通过元素化学分析,摩尔电导率和光谱(IR 和质量)研究进行了制备和表征。IR 光谱数据表明硫和亚甲胺氮参与与中心金属离子的配位。根据光谱研究,分配给 Zn(II)和 Hg(II)配合物的是四面体几何形状。游离配体及其金属配合物已在体外对多种微生物进行了测试,以评估它们的抗菌性能。
