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 Rgroups, intermolecular Bi … S interactions dominate the crystal packing in Bi(S2CNR2)3. |
