Abstract: 
Two one-dimensional bismuth trihalide coordination polymers (CPs) similar to 1 [BiCl3(4-cypy)2]n and similar to 1 BiBr3(4-cypy)2]n were obtained by the solvent free melt approach in molten 4-cyanopyridine under inert conditions and reduced pressure. The bismuth ions are surrounded by four halide atoms and two nitrogen atoms of the pyridyl ring of 4-cypy in trans-mode. The polymeric linkage of both CPs is achieved by halide-bismuth interactions while the 4-cyanopyridine ligands show pi-stacking interactions of their aromatic backbone. Both of compounds possess sufficiently intensive luminescence in the blue-green region of the visible spectra upon cooling to 77 K following the trend of halide anion influence on the position of the emission band. Emission of these CPs arises from the contribution of two energy transfer mechanisms, MLCT from Bi3+ to ligand and LMCT from ligand to Bi3+, respectively.
