“…For ligands in which R = 2-thienyl, 2-furyl, o-MeOPh and m-Pyr, only complexes of the lighter metals (Cu, Ni, Mn) have been structurally authenticated. The only main group examples structurally characterised [25] belong to a series of organotin(IV) complexes derived from 5-(phenyl)-1,3,4-oxadiazole-2-thione. This series highlights Scheme 1.…”

“…Thiolates predominate for more covalent Sn centres [-SnPh 3 , -Sn( c hex) 3 , -Sn(nBu) 3 ] [26] while in the oxido oligomer [-Sn(Me 2 )O-] the thioamide configuration is favoured. [25] In this study we report the synthesis of a new class of 5-substituted 1,3,4-oxadiazole-2-thiones, derived from various thiazoles, and their subsequent conversion to a series of homo-and heteroleptic bismuth(III) thiolates. The antibacterial activity of the Bi III complexes against Mycobacterium smegmatis, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), Enterococcus faecalis and Escherichia coli, and mammalian cell toxicity towards COS-7 monkey kidney cells, has been assessed and is reported alongside a comparison with our earlier studies into analogous bismuth(III) thiolates.…”

Seven novel 5‐substituted phenylthiazole oxadiazolethiones: [Me‐PTOT(H)], [MeO‐PTOT(H)], [MeS‐PTOT(H)], [F‐PTOT(H)], [Cl‐PTOT(H)], [Br‐PTOT(H)], and [CF3‐PTOT(H)], {where X‐PTOT(H) = 5‐[2‐(4‐X)thiazol‐4‐yl]‐1,3,4‐oxadiazole‐2(3H)‐thione, 4‐X = C6H4}, were synthesised from their corresponding thioamides. From these seven heteroleptic thiolatobismuth complexes: BiPh(Me‐PTOT)2 6, BiPh(MeO‐PTOT)2 7, BiPh(MeS‐PTOT)2 8, BiPh(F‐PTOT)2 9, BiPh(Cl‐PTOT)2 10, BiPh(Br‐PTOT)2 11 and BiPh(CF3‐PTOT)2 12 were synthesised and characterised. Complexes [10(DMSO)2] and [11(DMSO)2] were structurally characterised using X‐ray diffraction. Evaluation of the antibacterial properties of the thiones and their BiIII complexes against Mycobacterium smegmatis, Staphylococcus aureus (S. aureus), Methicillin‐resistant Staphylococcus aureus (MRSA), Vancomycin‐resistant Enterococcus (VRE), Enterococcus faecalis (E. faecalis) and Escherichia coli (E. coli) showed that all bismuth(III) complexes were highly effective against all the bacteria, as demonstrated by very low MIC values (1.1–2.1 μM). Complexes BiPh(Me‐PTOT)2 6, BiPh(Cl‐PTOT)2 10 and BiPh(Br‐PTOT)2 11, showed best activity against the multi‐drug resistant bacteria VRE and MRSA with an MIC value of 1.0 μM. All these complexes and their corresponding thiones failed to show any prominent activity against M. smegmatis and E. coli, even at high concentrations. These complexes showed little or no toxicity towards mammalian COS‐7 cells at 20 μg/mL.

In the title compound, [Ni(C9H6N3O3S)2(H2O)2]n, the NiII atom, located on an inversion center, is ligated in an octahedral geometry by two carboxylate O atoms from two 2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}acetate (L) ligands and two O atoms from water molecules in the equatorial plane, and two pyridine N atoms from other two L ligands at the apical sites. Two L ligands bridge pairs of metal atoms in an antiparallel manner, forming centrosymmetric dinuclear quasi-rectangular units which are linked into infinite double-stranded chains parallel to [100]. O—H⋯O hydrogen bonds between the coordinating water molecules and the carboxylate groups of the L ligand as well as interchain S⋯N interactions [2.726 (2)–3.363 (2) Å] lead to the formation of a layer structure parallel to (001).

Recycling Nanowire Templates for Multiplex Templating Synthesis: A Green and Sustainable Strategy

Template-directed synthesis of nanostructures has been emerging as one of the most important synthetic methodologies. A pristine nanotemplate is usually chemically transformed into other compounds and sacrificed after templating or only acts as an inert physical template to support the new components. If a nanotemplate is costly or toxic as waste, to recycle such a nanotemplate becomes highly desirable. Recently, ultrathin tellurium nanowires (TeNWs) have been demonstrated as versatile chemical or physical templates for the synthesis of a diverse family of uniform 1D nanostructures. However, ultrathin TeNWs as template are usually costly and are discarded as toxic waste in ionic species after chemical reactions or erosion. To solve the above problem, we conceptually demonstrate that such a nanotemplate can be economically recycled from waste solutions and repeatedly used as template.
