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

A series of crystal structures of tris(N,N-di-isobutyldithiocarbamato)bismuth(III), Bi(S 2 CN(iBu 2 )} 3 (1), tris(N,N-tetramethylenedithiocarbamato)bismuth(III), Bi{S 2 CN(CH 2 ) 4 } 3 (2), tris(N,N-hexamethylenedithiocarbamato)bismuth(III) chloroform solvate, Bi(S 2 CN(CH 2 ) 6 ) 3 ·CHCl 3 (3), and tris(N-methyl, N-phenyldithiocarbamato)-bismuth(III) hemi acetonitrile solvate, Bi(S 2 CN ·(Me)Ph) 3 ·0.5 CH 3 CN (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(S 2 CNR 2 ) 3 .
