Crystal growth and characterization studies of novel luminescent 2D coordination polymer of lead-benzilate possessing edge sharing PbO6 polyhedra

•2D coordination polymer is presented.•Crystals were obtained by gel diffusion technique.•Pb2O2 rings and chelate rings are present in the crystal structure.•The compound is transparent to all the visible radiations.•The compound exhibits intense luminescence.

Single crystals of a new coordination polymer of lead-benzilate, C28H21O6Pb·C2H5OH have been successfully grown by gel diffusion technique at room temperature. The colourless single crystals were obtained within a week. The crystal structure was elucidated using single crystal X-ray diffraction studies. The compound possesses a polymeric structure constructed from edge sharing PbO6 polyhedra. Single crystal X-ray diffraction analysis showed that the compound crystallizes in triclinic space group P-1. The grown crystals were further characterized by elemental analysis, FT-IR, UV–Visible and thermogravimetric analysis. The photoluminescent properties of the complex and the ligand were also investigated.
