A three-dimensional(3D) barium complex with 1,3,5-benzenetricarboxylic acid(H3BTC), {[Ba1.5(BTC)(H2O)]·(H2O)}n(1), was synthesized in DMF/EtOH/H2 O mixed solution under solvothermal conditions, and characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, thermogravimetric analyses, and photoluminescence measurement. In complex 1, the 2D I2O0 type inorganic layer is constructed by {Ba1O10} and {Ba2O9} polyhedra. Moreover, the solid-state fluorescence measurement reveals a fluorescence emission band at 465 nm under 344 nm excitation, assigned to a charge-transfer transition.
