The synthesis and characterization of bismuth halide-based coordination complexes is a difficult process due to the stereochemical activity at the bismuth center which causes the formation of various complexes with different coordination geometry in a single reaction. In this work we have designed a series of the bismuth halide (BiCl3, BiBr3, BiI3) based coordination complexes with an organic ligand in such way that the absorption of the complexes could be extended to the visible region of the spectrum and complexes can be studied photophysically. Therefore, to achieve the same, we incorporated the thiophene rings to highly coordinating bidentate 1,10-phenanthroline ligand and coordinated the organic ligand to different bismuth halides.
