“…The synthesized product I is stable to oxygen, moisture, and ambient light. Ligand L (3-benzyl-4-phenyl-1,2,4-triazol-5-thiol) was synthesized using the procedure similar to that reported earlier [73], of which its 1 H and 13 C NMR spectra (see Supplementary Information) are in good agreement with those reported previously. 1 H NMR (300 MHz, DMSO-d 6 ) δ: 3.86 (s, 2H, CH 2 ), 6.86-6.99 (m, 2H, C ar H), 7.14-7.28 (m, 5H, C ar H), 7.42-7.55 (m, 3H, C ar H), and 13.82 (broad s, 1H, SH).…”

“…The 13 C NMR spectrum of I could not be recorded due to the low solubility of the compound in the common deuterated solvents. When trying to accumulate data to record a 13 C NMR spectrum over a 24 h period, we also discovered that a white precipitate formed in the NMR ampoule. It is likely that deuterated dimethyl sulfoxide molecules replace pyridine and piperidine, reducing the solubility of complex I.…”

“…The current approach of advanced bioinorganic chemistry consists of using simple well-known biologically active molecules to design effective metallodrugs. Such ligands include, for example, benzimidazole derivatives [ 1 , 2 ]; purine bases [ 3 , 4 ], particularly caffeine [ 5 , 6 , 7 , 8 , 9 ]; the well-known commercially available ligand 1,10-phenanthroline [ 10 ]; anions of biologically active carboxylic acids (benzoic [ 11 , 12 ], 2-furoic [ 13 , 14 ], etc. ); dithiocarbamates [ 15 , 16 ]; and redox-active ligands [ 17 , 18 , 19 , 20 , 21 ].…”

A new silver(I) cluster [Ag8L4(Py)(Pype)]·4Py·11H2O (I) with 3-benzyl-4-phenyl-1,2,4-triazol-5-thiol (L) was synthesized via the direct reaction of AgNO3 and L in MeOH, followed by recrystallization from a pyridine–piperidine mixture. The compound I was isolated in a monocrystal form and its crystal structure was determined via single crystal X-ray diffraction. The complex forms a “butterfly” cluster with triazol-5-thioles. The purity of the silver complex and its stability in the solution was confirmed via NMR analysis. Excitation and emission of the free ligand and its silver complex were studied at room temperature for solid samples. The in vitro biological activity of the free ligand and its complex was studied in relation to the non-pathogenic Mycolicibacterium smegmatis strain. Complexation of the free ligand with silver increases the biological activity of the former by almost twenty times. For the newly obtained silver cluster, a bactericidal effect was established.

Various types, shapes and sizes of iron oxide nanoparticles were obtained depending on the nature of the precursor, preparation method and reaction conditions. The mixed valence trinuclear iron acetate, [Fe2 IIIFeIIO(CH3COO)6(H2O)3]·2H2O (FeAc1), μ3-oxo trinuclear iron(III) acetate, [Fe3O(CH3COO)6(H2O)3]NO3∙4H2O (FeAc2), iron furoate, [Fe3O(C4H3OCOO)6(CH3OH)3]NO3∙2CH3OH (FeF), iron chromium furoate, FeCr2O(C4H3OCOO)6(CH3OH)3]NO3∙2CH3OH (FeCrF), and an iron complex with an original macromolecular ligand (FePAZ) were used as precursors for the corresponding oxide nanoparticles. Five series of nanoparticle samples were prepared employing either a classical thermal pathway (i.e., thermal decomposition in solution, solvothermal method, dry thermal decomposition/calcination) or using a nonconventional energy source (i.e., microwave or ultrasonic treatment) to convert precursors into iron oxides. The resulting materials were structurally characterized by wide-angle X-ray diffraction and Fourier transform infrared, Raman, energy-dispersive X-ray, and X-ray fluorescence spectroscopies, as well as thermogravimetric analysis. The morphology was characterized by transmission electron microscopy, atomic force microscopy and dynamic light scattering. The parameters were varied within each route to fine tune the size and shape of the formed nanoparticles.
