Synthesis, single-crystal X-ray determination diffraction and FT-IR, NMR (¹H, ¹³C, ¹⁹F and ²⁰⁵Tl), 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) (1), Tl(5-metrop) (2), Tl(hino) (3), with Htrop, 5-methyltropolone (5-meHtrop), 4-isopropyltropolone (hinokitiol, Hhino), respectively, and additionally more complex {Tl@[Tl(hino)]₆}(OTf) (4) 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.

铊 (I) Tropolonates：与铅 (II) 和铋 (III) 类似物相比的合成、结构、光谱特征和抗菌活性

描述了一系列铊 (I) 化合物的合成、单晶 X 射线测定衍射和 FT-IR、NMR（¹ H、¹³ C、¹⁹ F 和²⁰⁵ Tl）、UV-vis 和发光光谱特征：铊(I) 三氟甲磺酸 (Tl(OTf))、三氟甲磺酸铊 (I) 和托酚酮 (Htrop) 的 1:1 共晶体、Tl(OTf)·Htrop 以及简单的铊 (I) 螯合物：Tl(trop) ( 1 ), Tl(5-metrop) ( 2 ), Tl(hino) ( 3 ), 分别与 Htrop, 5-methyltropolone (5-meHtrop), 4-isopropyltropolone (hinokitiol, Hhino), 以及更复杂的 { Tl@[Tl(hino)] ₆ }(OTf) ( 4） 化合物。将它们与选定的铅 (II) 和铋 (III) 类似物和游离配体的抗微生物活性进行比较表明，只有铋 (III) 配合物表现出显着的抗微生物活性，比游离配体大 2 到 5 倍。
