Abstract: The compound [4,4ʹ-H₂bipy][ZnBr₄] (1) has been synthesized via hydrothermal reaction and exhibits an isolated structure based on discrete 4,4ʹ-H₂bipy moieties and tetrahedral metal(II) centre terminally coordinated by four bromide ions. The organic moieties and the inorganic complex dianions are linked via hydrogen bonds forming a sheet structure. Optical absorption spectrum shows a band gap of 3.13 eV, indicating 1 to be a wide gap semiconductor. Luminescent investigation reveals a strong emission in blue region, which may be originating from π→π* charge-transfer interaction of 4,4ʹ-H₂bipy. IR, powder X-ray diffraction (PXRD) and thermogravimetry-differential thermal analyses (TG-DTA) are also reported
