摘　　要：A proton-transfer complex of 1,2,4,5-benzenetetracarboxylic acid（H4 BTC）with 1,10-phenanthroline（phen）[（H2BTC）^2-·2（Hphen）^＋·（H4BTC）]was synthesized and characterized by IR,UV-Vis spectra and luminescence. The structure was determined by X-ray single crystal diffraction.It crystallizes in the triclinic system,space group P-1 with a=7.3767（15）,b=10.704（2）,c=12.890（3）A.α=102.96（3）,β105.71（3）,γ=99.68（3）°,V=926.0（3）A^3,Dc=1.558g/cm^3,Z=2,μ（Mo-Kα）=0.121mm^-1 and F（000）=448.The final R=0.0401 and wR=0.0862 for 2983 observe reflections with[1〉2σ（I）].It is composed of discrete H4 BTC molecules,H2BTC^2- ANIONS AND [Hphen]^＋ cations.The extensive hydrogen-bonding associations fonned between the H4 BTC molecules and H2BTC^2- anions result in the formation of a two-dimensional layer,to which the [Hphen]^＋ cations are attached through the hydrogen bonds formed between the carboxyl groups of H4 BTC and the NH groups of [Hphen]^＋.Under the excitation of UV light.it emits an intense blue luminescence.A proton-transfer complex of 1,2,4,5-benzenetetracarboxylic acid（H4 BTC）with 1,10-phenanthroline（phen）[（H2BTC）^2-·2（Hphen）^＋·（H4BTC）]was synthesized and characterized by IR,UV-Vis spectra and luminescence.
