Abstract: We report the synthesis of single crystals of a metallorganic coordination compound, [Zn2Cl4(μ-bipy)2] , where bipy is 4,4′ -trimethylene bipyridine, which is capable of producing white light as a single component. The coordination compound was crystallized by the hydrothermal synthesis of zinc chloride and bipy ligand, and the structure was determined by single-crystal x-ray diffraction refinement. The [Zn2Cl4(μ-bipy)2] coordination complex crystallizes into a monoclinic crystal system in the P21/m space group. The coordination compound is a distinct single-component, white-light-emitting phosphor upon excitation by UV-light-emitting diodes. The internal quantum efficiency was found to be 32%. The crystal structure and photoluminescence properties of the coordination polymer are discussed.
