Synthesis and Characterization of Ni2+, Cu2+ and Zn2+ Complexes with Benzimidazole-2-thionate, Diphosphene and Their Reaction with Iodine

Abstract: There has been considerable interest in the study of organic ligands containing two or more different donor atoms because such ligands through light on the nature of the metalligands bonding. Selenium and bismuth metals react with di-2-pyridyldisulfide (Py2S2) in refluxing toluene to give the compounds Se(pyS)4 and Bi(pyS)3 in high yield. Reactions of selenium or bismuth/Py2S2 and iodine in different molar ratio was carried out in refluxing toluene led to the formation of Se(pyS)3I, Se(pyS)2I2, Bi(pyS)2I and B… Show more

“…Zn(II) complexes are diamagnetic and exhibited no band in their electronic spectra. However, on the basis of microanalytical data the complexes found to be six coordinated, for which octahedral symmetry is the most preferred symmetry [53][54][55].…”

“…e IR spectra of the complexes 1-4 appear as a band at 734-739 cm −1 assigned to ρ(H 2 O), which indicates the presence of coordinated water [18]. Metal-oxygen, M-nitrogen, and M-phosphorus vibration bands appear at 504-510, 470-482, and 432-448 cm −1 district, respectively (Figure 2) [30,31].…”
