A new linear bismuth(III) coordination polymer, catena-poly[[chloridobismuth(III)]-mu(3)-1,10-phenanthroline-2,9-dicarboxylato-kappa O-6(2):O-2,N-1,N-10,O-9:O-9], [Bi(C14H6N2O4)Cl](n), has been obtained by an ionothermal method and characterized by elemental analysis, energy-dispersive X-ray spectroscopy, IR spectroscopy, thermal stability studies and single-crystal X-ray diffraction. The structure is constructed by Bi(C14H6N2O4) Cl fragments in which each Bi-III centre is seven-coordinated by one Cl atom, four O atoms and two N atoms. The coordination geometry of the Bi-III cation is distorted pentagonal-bipyramidal (BiO4N2Cl), with one bridging carboxylate O atom and one Cl atom located in the axial positions. The Bi(C14H6N2O4) Cl fragments are further extended into a one-dimensional linear polymeric structure via subsequent but different centres of symmetry (bridging carboxylate O atoms). Neighbouring linear chains are assembled via weak C-H center dot center dot center dot O and C-H center dot center dot center dot Cl hydrogen bonds, forming a three-dimensional supramolecular architecture. Intermolecular pi-pi stacking interactions are observed, with centroid-to-centroid distances of 3.678 (4) angstrom, which further stabilize the structure. In addition, the solid-state fluorescence properties of the title coordination polymer were investigated.
