A new linear bismuth(III) coordination polymer, catena ‐poly[[chloridobismuth(III)]‐μ 3 ‐1,10‐phenanthroline‐2,9‐dicarboxylato‐κ 6 O 2 : O 2 , N 1 , N 10 , O 9 : O 9 ], [Bi(C 14 H 6 N 2 O 4 )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(C 14 H 6 N 2 O 4 )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 (BiO 4 N 2 Cl), with one bridging carboxylate O atom and one Cl atom located in the axial positions. The Bi(C 14 H 6 N 2 O 4 )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...O and C—H...Cl hydrogen bonds, forming a three‐dimensional supramolecular architecture. Intermolecular π–π stacking interactions are observed, with centroid‐to‐centroid distances of 3.678 (4) Å, which further stabilize the structure. In addition, the solid‐state fluorescence properties of the title coordination polymer were investigated.
