Summary: At physiological pH, bismuth binds to apo-MT3 and forms a novel Bi2S5 species with a bridging cysteine, resulting in a bright yellow color from absorption at 460 nm. The binding affinity and structure of Bi3+ in apo-MT3 were investigated using various spectroscopic techniques, revealing the formation of a highly cooperative Bi(2)MT3 species that is coordinated by three cysteinyl thiolates, with one thiolate bridging between two Bi3+ ions. This discovery highlights the presence of bridging cysteines for bismuth in MT3 and the first reported Bi cluster in a metalloprotein.

Summary: The oxido clusters of bismuth have attracted increasing attention in recent decades. This is due to the use of bismuth compounds as pharmaceuticals and their interesting properties. The structures of the oxido species are similar to solid state bismuth oxides, and the chemistry of the oxido clusters is closely related to the coordination chemistry of bismuth. Various ligands have been used to support the formation of these structures. The review summarizes the synthetic methods, physical and chemical properties, and structures of bismuth oxido clusters.

Summary: The global prevalence of antimicrobial resistance (AMR) is increasing, presenting a significant global health challenge. Bacterial resistance reduces antibiotic effectiveness and raises morbidity and mortality. Novel coordination compounds were investigated for their antibacterial potential using transition divalent metal ions and the decanoic acid ligand. Spectroscopic techniques confirmed complex formation, while scanning electron microscopy analyzed their unique morphologies. Metal decanoates showed promising bactericidal activity against both Gram positive and negative bacteria, as well as enhanced antifungal effects. These findings highlight metal decanoate complexes as potential candidates for mitigating antimicrobial resistance.

Summary: Chemists prefer to use transition metal hydride complexes rather than thiolate complexes for catalyzing chemical transformations due to their diverse reactivity, despite being sensitive to air/moisture and difficult to prepare. This review demonstrates that transition metal thiolate complexes are superior catalysts to the corresponding hydride complexes in catalyzing the hydroboration and hydrosilylation of C=O and C=N bonds. The thiolate complexes show higher activity in these reactions and can catalyze many of the reactions previously catalyzed by hydride complexes. Hence, the future application of transition metal thiolate complexes in catalytic hydroboration and hydrosilylation of unsaturated carbon-heteroatom bonds deserves special attention.

Summary: Synthesized 5-cyano-6-phenyl-2-thiouracil (H2CPT) combined with trivalent (Cr(III), Fe(III)) and divalent (Co(II), Ni(II), Cu(II) Zn(II)) metal ions and 1,10-phenanthroline monohydrate (Phen), resulting in crystalline and semi-crystalline nanoparticles mixed ligand metal complexes. Various techniques were used to investigate the physicochemical and spectroscopic properties of the complexes, including FT-IR, UV-Vis, 1H NMR, XRD, and thermal analyses. The complexes exhibited ionic behavior and octahedral geometries, with semi-crystalline or crystalline nature depending on the metal ions. The complexes showed significant antibacterial and antifungal activity, with the Co(II) complex being the most effective.

Summary: This study synthesized and characterized twelve Re(i) tricarbonyl diimine complexes with thiotetrazolato ligands. The tetrazolato ligand can bind to the Re(i) center through either the S atom or the N atom, with most complexes being bound to the N atom. In solution, the complexes exist as an equilibrating mixture of linkage isomers. The complexes exhibit photoluminescent properties, with emission wavelengths dependent on the nature of the diimine ligand.
