“…[29] Indicative of the complexes adopting the thiolate anion upon deprotonation, a longer C-S bond length S(1)-C (7) 2 ]} are obtuse in nature and far removed from the expected bond angle of 109°seen in other similar Bi-S-C bonded complexes. [30] These obtuse Bi-S-C angles are similar to the previously reported bismuth(III) thiolate complexes [BiPh(2-MMI) 2 -{2-MMI(H)} 2 ] (2-MMI = 2-thiolate-1-methylimidazole [Bi-S-C average: 93.50°]), [31] and {BiPh(4-MTT) 2 [4-MTT-(H)] 2 } (4-MMT = 4-methyl-1,2,4-triazole-3-thiolate) [29] which adopt the same distorted square pyramidal geometry seen in complexes [10(DMSO) 2 2 ], the discrete molecular units form a head to tail arrangement maximising significant intra-(average centroid distance: 3.717 Å) and intermolecular (average centroid distance: 3.605 Å) π-stacking of the oxadiazolethiolate ligands which can be seen in Figure 5. …”

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.

“…The fluorinated thiolate SC 6 F 5 has been used similarly in s-, p-, d-, and f-block − research, again giving products with superior solubility properties and leading to the formation of products with distinctive structural characteristics. Most recently, these SC 5 F 6 ligands were used to make a series of (DME) 2 Ln(SC 6 F 5 ) 3 (Ln = Nd, Er, and Tm) coordination complexes that had, at that time, the highest near-infrared (NIR) emission quantum efficiencies ever reported for molecular lanthanide sources.…”

Reductive cleavage of C(6)F(5)SeSeC(6)F(5) with elemental M (M = Zn, Cd, and Hg) in pyridine results in the formation of (py)(2)Zn(SeC(6)F(5))(2), (py)(2)Cd(SeC(6)F(5))(2), and Hg(SeC(6)F(5))(2). Structural characterization of the Zn and Cd compounds reveals tetrahedral coordination environments, while the Hg compound shows a complicated series of linear structures with two short, nearly linear Hg-Se bonds, up to two longer and perpendicular Hg...Se interactions, and no coordinated pyridine ligands. All three compounds exhibit well-defined intermolecular pi-pi-stacking interactions in the solid state. They are volatile and decompose at elevated temperatures to give MSe and either (SeC(6)F(5))(2) or Se(C(6)F(5))(2).

“…Fluorinated chalcogenolate are relatively unexplored throughout the periodic chart when compared with hydrocarbon analogues, with syntheses often motivated by the tendency of ring fluorination to form compounds with unusual physical properties, i.e., stability of high oxidation states or compound volatility. Fluorinated thiolates have been examined with the s-, p-, and d-block metals, as well as a number of highly NIR emissive lanthanide compounds, while analogous selenolates are thus far limited to a handful of main group examples , and a single example from the lanthanide series.…”

Thorium chalcogenolates Th(ER)4 (E = S, Se; R = Ph, C6F5) form pyridine complexes with a variety of coordination numbers. Four compounds, (py)4Th(SPh)4, (py)3Th(SePh)4, (py)3Th(SC6F5)4, and (py)4Th(SeC6F5)4, have been isolated and characterized by spectroscopic methods and low-temperature single crystal X-ray diffraction. Two of the products, (py)4Th(SPh)4 and (py)4Th(SeC6F5)4, have classic eight coordinate A4B4 square-antiprism geometries. The SePh compound is the only seven coordinate (4Se, 3N) product, and the fluorinated thiolate is distinctive in that the structure contains two dative interactions between Th and fluoride, to give a nine coordinate (3N, 4S, 2F) structure. The EPh compounds decompose thermally to give ThE2 and EPh2, while the fluorinated compounds give primarily ThF4, E2(C6F5)2, and E(C6F5)2.
