TLDR
In this paper, six bismuth(III) complexes containing dithio-ligands formulated as (R2NCS2)3Bi [R2 NCS2M]3Bi] and (R 2NCS 2M 2BiI]2 ] were obtained by reactions of halides with dithiocarbamate ligands in 1 or 1/3 stoichiometry.Abstract:
Six bismuth(III) complexes containing dithio-ligands formulated as (R2NCS2)3Bi [R2NCS2M = Me2NCS2Na, C4H8NCS2Na, Bz2NCS2Na] and [(R2NCS2)2BiI]2 [R2NCS2M = C5H10NCS2Na, n Bu2NCS2Na, OC4H8NCS2Na] have been obtained by reactions of bismuth(III) halides with dithiocarbamate ligands in 1 : 2 or 1 : 3 stoichiometry All compounds were characterized by elemental and IR analyses The crystal structures of complexes 1 and 4 have been determined by X-ray single crystal diffraction The structure analyses reveal that BiIII in complex 1 adopts a distorted pentagonal–pyramidal coordination, due to its stereochemically active lone pair of electrons A long Bi · S contact of 3218 (3) A leads to dimeric associations of molecules in the crystal structure The structure of complex 4 is six-coordination with a distorted octahedral configuration Intramolecular S · S weak interactions contribute to the stability and lead to a one-dimensional chain structureread more
