single-crystal diffraction analysis of two complexes and by a FT-IR study of all complexes. The [Re(CO)3(bqui)(Bzpy)](CF3SO3) complex crystallizes in the form of two mirror isomers arising from the conformational mobility of the biquinoline ligand. A correlation between the metal-to-ligand charge-transfer (MLCT) emission maxima and the σ+Hammett parameter was established for the complexes of the bqui series
