Coordination polymers formed by Bi(SC6F5)3 with multidentate polypyridyl ligands

The reaction between the bismuth(III) thiolate Bi(SC6F5)(3) and the bis(4-pyridyl) ligands 4,4'-bipyridyl (4,4'-bipy), 1,2-bis(4-pyridyl) ethane or trans-1,2-bis(4-pyridyl) ethene in either thf (tetrahydrofuran) or dmf (dimethylformamide) solution affords, after crystallisation, the one-dimensional polymeric structures {[Bi(SC6F5)(3)(thf)(4,4'-bipy)]}(infinity), {[Bi(SC6F5)(3)(dmf){1,2-bis(4-pyridyl)ethane}]}(infinity) and {[Bi(SC6F5)(3)((t)hf){trans-1,2-bis(4-pyridyl)ethene}].thf}(infinity). A related one-dimensional polymeric structure is observed when the tris-4-pyridyl ligand 2,4,6-tris(4-pyridyl)-1,3,5-triazine is employed, namely {[Bi(SC6F5)(3){2,4,6-tris(4-pyridyl)-1,3,5-triazine}]}(infinity), whereas with 2,4,6-tris-2-pyridyl-1,3,5-triazine, a monomeric complex [Bi(SC6F5)(3){2,4,6-tris(2-pyridyl)-1,3,5-triazine}] is obtained.
