Abstract

Two tetranuclear lantharide-based complexes: [Yb₄(μ₃-OH)₂(acac)₄(L¹)₆] (1) and [Yb₄(μ₃-OH)₂(acac)₄(L²)₆]·2CH₃CN (2) (Hacac = acetylacetone; HL¹ = (Z)-5-((4-methoxybenzylidene)amino)-8-hydroxyquinoline; and HL² = (Z)-5-((4-ethoxybenzylidene)amino)-8-hydroxyquinoline) were constructed and structurally characterized. These complexes are members of the triclinic crystal structure with space group P − 1, according to X-ray diffraction research. The structure of complexes 1 and 2 is isostructural, while the four Yb^III ions are joined by μ₃-O to create a parallelogram core, giving the whole molecule a butterfly-shaped structure. Additionally, studies on biological activity show that the complexes 1 and 2 exhibit superior antibacterial properties compared to ligands HL¹, HL², and Yb(acac)₃·2H₂O against Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Candida albicans. Research has also been done on the interactions between complexes 1 and 2 and CTDNA, and the findings indicate that complexes 1 and 2 are primarily intercalated with CTDNA.

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.
