A series of diorganotin (IV) complexes of the types of R ₂SnCl(SSCC₃H₃N₂) (R = CH₃ 1, ⁿBu 2, C₆H₅ 3 and C₆H ₅CH₂ 4), R₂Sn(SSCC₃H ₃N₂)₂ (R = CH₃ 5, ⁿBu 6, C₆H₅ 7 and C₆H₅CH₂ 8) and R₂Sn(SSCC₃H₂N₂) (R = CH₃ 9, ⁿBu 10, C₆H₅ 11 and C₆H ₅CH₂ 12) have been obtained by reactions of 4(5)-imidazoledithiocarboxylic acid with diorganotin (IV) dichlorides in the presence of sodium ethoxide. All complexes are characterized by elemental, IR, ¹H, ¹³C and ¹¹⁹Sn NMR spectra analyses. Also, the complexes 1, 7 and 9 are characterized by X-ray crystallography diffraction analyses, which reveal that the complex 1 is monomeric structure with five-coordinate tin (IV) atom, the complex 7 is monomeric structure with six-coordinate tin (IV) atom and the complex 9 is one-dimensional chain with five-coordinate tin (IV) atom.
