Biological important ternary complexes of type [HgL(A-A)] [where L = 2-(2-hydroxynaphthyl)benzothiazole (APBT), 2-(2-hydroxyphenyl)benzothiazole (HPBT), 2-(2-mercapto-phenyl)benzothiazole (MPBT)] (A = glycine or alanine) have been synthesized and characterized by m.w. determination, magnetic measurements, infrared and NMR studies. A tetrahedral geometry has been proposed for the present mercury(II) complexes. All the complexes are coloured, thermally stable, monomeric and non-electrolytic in nature. The ligands and their metal complexes showed biological activity against pathogenic fungi Aspergillus niger and Fusarium oxysporum. The antifungal activity data revealed that mercury(II) complexes are found more fungi-toxic than the parent ligands.
生物学上重要的三元复合物类型 [HgL(A-A)] [其中 L = 2-(2-羟基萘)苯噻唑 (APBT)、2-(2-羟基苯)苯噻唑 (HPBT)、2-(2-巯基苯)苯噻唑 (MPBT)] (A = 甘氨酸或丙氨酸) 已被合成并通过分子量测定、磁性测量、红外光谱和核磁共振研究进行了表征。对当前的汞(II)复合物提出了四面体几何结构的假设。所有复合物均为有色、热稳定、单体且无电解质性质。配体及其金属复合物展现出对致病真菌黑曲霉和镰刀菌的生物活性。抗真菌活性数据显示,汞(II)复合物的真菌毒性高于其母体配体。
