New tetrahedral, square-pyramidal, trigonal-bipyramidal and octahedral organotin(IV) 4-ethoxycarbonylpiperazine-1-carbodithioates: Synthesis, structural properties and biological applications

Trimethyltin(IV) Bearing 3-(4-Methyl-2-oxoquinolin-1(2H)-yl)propanoate Causes Lipid Peroxidation-Mediated Autophagic Cell Death in Human Melanoma A375 Cells

“…The geometry around the tin atom in Me 3 SnL was also confirmed by the 119 Sn NMR study. In general, chemical shifts for tetracoordinated organotin(IV) complexes are found in the range from 200 to −60 ppm, those for pentacoordinated complexes are in the range from −90 to −190 ppm and those for hexacoordinated complexes are in the range from −210 to −400 ppm [ 45 , 46 ]. The 119 Sn NMR spectrum for Me 3 SnL showed tin resonance at 130 ppm, suggesting tetrahedral geometry around the tin atom in non-polar solvents, and this is in agreement with other tetracoordinated trimethyltin(IV) carboxylates [ 45 ].…”

“…Dithiocarbamate ligands are versatile ligands with applications in industry [1], agriculture [2] and biology [3]. Since these ligands contain nitrogen and sulfur donor atoms, they are capable of forming complexes with most of the elements [4].…”
