Synthesis, single-crystal X-ray determination diffraction and FT-IR, NMR (H, C, F and Tl), UV-vis, and luminescence spectra characteristics were described for series of thallium(I) compounds: thallium(I) triflate (Tl(OTf)), 1:1 co-crystals of thallium(I) triflate and tropolone (Htrop), Tl(OTf)·Htrop, as well as simple thallium(I) chelates: Tl(trop) (), Tl(5-metrop) (), Tl(hino) (), with Htrop, 5-methyltropolone (5-meHtrop), 4-isopropyltropolone (hinokitiol, Hhino), respectively, and additionally more complex {Tl@[Tl(hino)]}(OTf) () compound. Comparison of their antimicrobial activity with selected lead(II) and bismuth(III) analogs and free ligands showed that only bismuth(III) complexes demonstrated significant antimicrobial activity, from two- to fivefold larger than the free ligands.
我们描述了一系列铊（I）化合物的合成、单晶 X 射线衍射及 FT-IR、NMR（H、C、F 和 Tl）、UV-vis 和发光光谱特性：三氟甲磺酸铊（Tl(OTf)）、三氟甲磺酸铊和三羟甲基三亚甲基尿嘧啶（Htrop）的 1:1 共晶、Tl(OTf)·Htrop，以及简单的铊（I）螯合物：三羟甲基三亚甲基尿嘧啶（）、5-甲基三羟甲基三亚甲基尿嘧啶（）、三羟甲基三亚甲基尿嘧啶（），分别与 Htrop、5-甲基三羟甲基三亚甲基尿嘧啶（5-meHtrop）、4-异丙基三羟甲基三亚甲基尿嘧啶（hinokitiol，Hhino）配合，此外还有更复杂的{ Tl@[Tl(hino)]}(OTf) ()化合物。将它们的抗菌活性与选定的铅（II）和铋（III）类似物和游离配体进行比较表明，只有铋（III）配合物表现出显著的抗菌活性，比游离配体大两到五倍。
