摘要

本研究旨在研究以单晶形式合成的含硼多金属氧酸盐（BPOM） Na7[H1.5BW12O40]∙6en(1)的抗菌活性。利用FT-IR， TGA和x射线衍射（XRD）技术对这种新型BPOM的结构和热性能进行了全面分析。在这些结构中加入硼被认为可以增强它们的抗菌性能。采用盘扩散和管稀释（最小抑制浓度）法对2种革兰氏阳性菌（金黄色葡萄球菌、蜡样芽孢杆菌）、3种革兰氏阴性菌（大肠埃希菌、军团菌、嗜肺军团菌sg 2-15）和1种酵母菌（白色念珠菌）进行抑菌活性评价。结果表明，合成的化合物对蜡样芽孢杆菌（革兰氏阳性）、军团菌和嗜肺军团菌sg - 15（革兰氏阴性）具有显著的抑菌活性。

Sodium salt of boron-substituted first keggin-type polyoxometalate; synthesis, crystal structure and investigation of antimicrobial activities

This study aims to investigate the antimicrobial activity of the boron-containing polyoxometalate (BPOM) Na₇[H_1.5BW₁₂O₄₀]∙6en (1), synthesized as a single crystal. The structural and thermal properties of this novel BPOM were thoroughly analyzed using FT-IR, TGA, and X-ray diffraction (XRD) techniques. The incorporation of boron into these structures is believed to enhance their antimicrobial properties. The antimicrobial activity of the compound was evaluated against two Gram-positive bacteria (Staphylococcus aureus, Bacillus cereus), three Gram-negative bacteria (Escherichia coli, Legionella spp., Legionella pneumophila sg 2–15), and a yeast (Candida albicans) using disc diffusion and tube dilution (Minimal Inhibition Concentration) methods. The results demonstrated that the synthesized compound exhibited significant antimicrobial activity, particularly against Bacillus cereus (Gram-positive) and Legionella spp. and Legionella pneumophila sg 2–15 (Gram-negative).

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
