Synthesis, characterization and biological evaluation of octyltrimethylammonium tetrathiotungstate

Abstract: Octyltrimethylammonium tetrathiotungstate salt (ATT-C8) was synthesized and its ability to chelate copper was evaluated. The biological and toxic aspects were evaluated by in vitro and in vivo assays, using bovine aorta endothelial cells (BAEC) and zebrafish (Danio rerio) embryos. The obtained results suggest that ATT-C8 has better biocompatibility, showing a significantly lower lethal concentration 50 (LC50) value in comparison to ammonium tetrathiotungstate (ATT). Zebrafish embryos assay results indicate that both tetrathiotungstate salts at the studied concentrations increase the hatching time. Even more, an in vivo assay showed that synthesized materials behave as copper antagonists and have the ability to inhibit its toxicological effects. Also, both materials were found to be active for the in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The characterization of the materials was carried out using the following spectroscopic techniques: Ultraviolet–Visible (UV–Vis), Fourier Transform Infrared (FTIR) and proton nuclear magnetic resonance (1H-NRM).

Facile syntheses of new molybdenum and tungsten sulfido complexes. Structure of Mo3S92-

Heating (NH4)2MS4 (M = W, Mo) in N,N-dimethylformamide leads to the formation of the trinuclear ions M3S92-. Under similar conditions but in the presence of 1,2-ethanedithiol (edtH2) or o-aminobenzenethiol (abtH2) the dinuclear ions M2S4(edt)22- or M2S4(abt)22- are formed. The complex (PPh4)2Mo3S9 (Ph = C6H5) crystallizes in the space group P1 (Z = 1) with unit cell dimensions a = 9.100 (2) ?, b = 10.531 (5) ?, c = 13.286 (6) ?, α = 87.02 (4)°, β = 84.99 (2)°, and γ = 83.56 (2)°. The structure shows two external tetrahedral MoS4 units chelating a central square-pyramidal MoS unit. The Mo-Mo-Mo angle is 155.0 (1)°. Key distances (A) are as follows: Mo-S(terminal to central Mo) = 2.086 (4); Mo-S(terminal to external Mo) = 2.134 (4), 2.145 (4), 2.136 (3), 2.148 (3); Mo-S(bridge to external Mo) = 2.231 (3), 2.247 (3), 2.251 (3), 2.234; Mo-S(bridge to central Mo) = 2.429(3), 2.369 (3), 2.389 (3), 2.388 (3); Mo-Mo = 2.982 (1), 2.924 (1). The cyclic voltammetry of the trinuclear complexes is reported. The complexes M3S92- are formulated as mixed-valence VI, IV, VI compounds, and a mechanism is proposed for their formation.
