A zinc(II) complex of polypyazole containing ligand namely, [Tp*ZnCl] (Zn1) {Tp* = tris(3,5-dimethylpyrazolyl)borate}, along with its bound hydroxo [Tp*Zn–OH] (Zn2) were synthesized and characterized by FT-IR, Raman, 1H NMR techniques elemental analysis. In alkaline solution (0.1 M KOH), the Zn2 modified glassy carbon (GC), namely GC–Zn2, was investigated as a molecular electrocatalyst for hydr...
Late Neoproterozoic metamorphic – igneous rocks of the Shotor Kuh complex is located in the northern edge of the Central Iran structural zone. This complex crosscut by several Middle Jurassic diabasic dikes. Plagioclase, pyroxene and biotite are the essential rock-forming minerals of these dikes. Plagioclases have mostly andesine composition (An31-49). Pyroxenes have following compositions: En3...
Recently, 6-(2-naphthyl)-2, 3-dihydro-as-triazine-3-thione (NDTT) was synthesized in laboratory and used successfully for the spectrophotometric determination of nanogram levels of Cu2+ in aqueous solution. This reagent forms a specific red complex with Cu2+ ions after the extraction by chloroform at alkaline pH. The absorption of the complex in the UV region (313 nm) is about 8 times as strong...
