New Advances in Chemical Research, May 2021. We’ll be discussing some of the latest developments in chemical about CAS: 489-84-9. In an article, author is Mahato, Mamata, once mentioned the application of 489-84-9, Name is Guaiazulene, molecular formula is C15H18, molecular weight is 198.3034, MDL number is MFCD00003811, category is thiomorpholine. Now introduce a scientific discovery about this category, Reference of 489-84-9.
Six mononuclear organotin(IV) complexes of two dithiocarbamato ligands, [Ph3SnL1] (1), [Bu2Sn(L-1)(2)] (2), [Ph2Sn(L-1)Cl] (3), [Ph2Sn(L-1)(2)] (4), [Ph2Sn(L-2)(2)] (5) and [Ph3Sn(L-2)] (6) where L-1 = thiomorpholine-4-carbodithiolate and L-2 = 2,6-dimethylmorpholine-4-carbodithiolate have been synthesized in good yields. Both ligands and complexes 1-6 were characterized by elemental analyses, FT-IR spectroscopy, UV-visible spectroscopy and H-1, C-13{H-1} Sn-119{H-1} NMR spectroscopy. In addition, the solid-state structures of the complexes were established through single-crystal X-ray diffraction analyses. The Xray analyses reveal that the Sn(IV) center is five-coordinated in 1, 3 and 6. In complexes 2, 4 and 5, Sn(IV) is six-coordinated and occupies the center of a distorted octahedron. Moreover, an asymmetric coordination mode of the dithiocarbamato ligands was observed in all complexes. The optical properties and thermal stabilities of all complexes were investigated. All complexes were evaluated for their in vitro antimicrobial properties against E. coli. Complex 1 shows a maximal biological activity whereas the least activity is found for complex 6.
