Chiral lanthanide(III) complexes of sulphur–nitrogen–oxygen ligand derived from aminothiourea and sodium D-camphor-β-sulfonate

Chiral Lanthanide Complexes: Coordination Chemistry and Applications

“…The homomoleptic tris(camphorsulfonates) [Ln( 26 ) 3 ] are prepared by reaction of H 26 with Ln(ClO 4 ) 3 in anhydrous EtOH, and the heteroleptic complexes [Ln(phen) 2 Cl( 26 ) 2 ] are prepared by reaction of [Ln(phen) 2 Cl 3 ] with Na 26 . Complexes of the camphorsulfonate-derived Schiff bases 27 and 28 have also been reported; they are formulated as [Ln(H 27 )( 27 )] and [Ln( 28 ) 3 ] . All of these complexes have been studied spectroscopically (including CD spectra), but none has yet been characterized crystallographically.…”

Potential anticancer activity of Mn (II) complexes containing arginine dithiocarbamate ligand on MCF-7 breast cancer cell lines

“…Meanwhile, the C - S bond group occurs at wave numbers 550–800 cm −1 , and the C = S at 1050-1200 cm −1 [ 11 ]. Furthermore, the bonds between the metal and the ligands are observable from the far infrared absorption ranging from the wave number 400-100 cm −1 , as seen in the linkages formed between sulfur or nitrogen and metals [ 12 ].…”

“…Dithiocarbamate is a uniquely structured compound, owing to the presence of S group as both a monodentate and bidentate electron donor. These compounds bond predominantly with transition metals to form complexes, an example seen with manganese metals [ [11] , [12] , [13] ]. Meanwhile, the use of these ligands with arginine as an additional donor increases the diversity of the complex structure, and also influences the biological activity [ 14 ].…”

Potential of Breast Anticancer Compounds (MCF-7) from Synthesis Results and Characterization of Complex Compounds of Mg(II) Isoleucinedithiocarbamate

“…The dithiocarbamate complex compound that has a v (C = N) bond was obtained from v uptake (C-N) which was located in the wave number between single bonds (1350-1250) cm -1 and double bonds (1690-1640) cm -1 . Whereas CS absorption lies in wavelength number between single CS (550-800) cm -1 and double bond C = S (1050-1200) cm -1 so that the bond was written as v (C = S) [11,14]. Strain of sulfur metal bonds from ditiocarbamate ligands and metal bonds with nitrogen from bipyridyl or phenantroline ligands showed the bond between metals and ligands which observed from far infrared absorption (400-100) cm -1 .…”

“…Strain of sulfur metal bonds from ditiocarbamate ligands and metal bonds with nitrogen from bipyridyl or phenantroline ligands showed the bond between metals and ligands which observed from far infrared absorption (400-100) cm -1 . [14][15] Based on table 2., infrared absorption peaks at wave number 391 cm -1 showed the interaction of S atoms with metal ions Mg. The absorption peak at wave number 486 cm -1 showed the interaction of O atoms of complex compounds with metal ions Mg.…”
