Thiol-functionalized mesostructured silica with anhydrous compositions of (SiO(2))(1)(-)(x)()(LSiO(1.5))(x)(), where L is a mercaptopropyl group and x is the fraction of functionalized framework silicon centers, are effective trapping agents for the removal of mercuric(II) ions from water. In the present work, we investigate the mercury-binding mechanism for representative thiol-functionalized ...

Abstract Thiolate-protected gold nanoclusters (AuNCs) have been intensively studied due to their appealing physicochemical properties that can be used in various applications, especially catalysis. However, thiolate-protected AuNCs a free suspension form, tend aggregate during catalytic reaction the high surface reactivity of its ultrasmall size, hence, reducing rate reaction. Their recovery an...

The uncontrolled concentrations of heavy metals introduced into the water sources need an effective method for their removal. dithiocarbamate (dtc) ligands are most popular precipitating agents used removal from wastewater. Presently, two novel dtc ligands, one without methylene linker (K2L1) and other with (K2L2) were eight ions including Fe2+, Co2+, Ni2+, Cu2+, Cd2+, Ag+, Zn2+ Pb2+ aqueous so...

Abstract A polyhydrido copper nanocluster, [Cu 14 H 10 (PPh 3 ) 8 (SR) ] + (HSR = 2,4-dimethylbenzenethiol), adopting a distorted fcc structure, is reported. One cube-vertex atom, coordinated by the three thiolate ligands and PPh , protrudes outwards from metal framework. The twisting of about threefold axis lowers symmetry O h (Cu to C forming racemic pairs intrinsic chiral clusters in crystal...

Zinc thiolate complexes containing N2S tridentate ligands were prepared to investigate their reactivity toward reactive nitrogen species, chemistry proposed to occur at the zinc tetracysteine thiolate site of nitric oxide synthase (NOS). The complexes are unreactive toward nitric oxide in the absence of dioxygen, strongly indicating that NO cannot be the species directly responsible for S-nitro...

Although atomically precise metalloid nanoclusters (NCs) of identical size with distinctly different molecular structures are highly desirable to understand the structural effects on optical and photophysical properties, their synthesis remains challenging. Herein, we employed phosphine thiol capping ligands featuring appropriate steric synthesized a charge-neutral Ag NC formula Ag44 (EBT)26 (T...

Thiolate complexes continue to attract considerable attention due to their unique chemical properties and structural diversity. Since thiolate groups meet the electronic and steric requirements necessary to stabilize a wide variety of metal complexes, they have been used as auxiliary ligands. On the other hand, thiolate complexes are known to undergo chemistry at the sulfur center, including ox...

The fluorinated tris-thiolate compounds Ln(SC(6)F(5))(3) can be isolated as THF, pyridine, or DME coordination complexes. In THF, the larger Ce forms dimeric [(THF)(3)Ce(SC(6)F(5))(3)](2) (1) with bridging thiolate ligands, while the smaller lanthanides (Ln = Ho (2), Er (3)) form monometallic (THF)(3)Ln(SC(6)F(5))(3) compounds. There is a tendency for fluoride to coordinate to Ln throughout the...
