Prevalance of intermolecular Bi … S interactions in bismuth dithiocarbamate compounds: Bi(S₂CNR₂)₃

Keywords: Bismuth, Dithiocarbamate, Secondary interactions, Bi . . . S interactions, Crystal structure analysis

A series of crystal structures of tris(N,N-di-isobutyldithiocarbamato)bismuth(III), Bi{S₂CN(iBu₂)}₃ (1), tris(N,N-tetramethylenedithiocarbamato)bismuth(III), Bi{S₂CN(CH₂)₄}₃ (2), tris(N,N-hexamethylenedithiocarbamato)bismuth(III) chloroform solvate, Bi(S₂CN(CH₂)₆)₃ · CHCl₃ (3), and tris(N-methyl, N-phenyldithiocarbamato)-
bismuth(III) hemi acetonitrile solvate, Bi(S₂CN · (Me)Ph)₃ · 0.5 CH₃CN (4) has been determined and each structure shows the presence of three chelating dithiocarbamate ligands as well as two (in (1) and (2)) or one (in (3) and (4)) intermolecular Bi … S interactions leading to the formation spherical dimeric aggregates. The conclusion of this structural study is that regardless of the size of the dithiocarbamate-bound R groups, intermolecular Bi … S interactions dominate the crystal packing in Bi(S₂CNR₂)₃.
