A heterometal-organic framework {[Pr2Ca（betc）2（H2O）7]·H2O}n（1） was prepared by the hydrothermal reaction of 1,2,4,5-benzenetetracarboxylic acid（H4betc） with Pr（NO3）3 and CaCO3, and further characterized by single-crystal X-ray structural analysis, elemental analysis, IR, thermal gravimetric, and X-ray powder diffraction. Complex 1 crystallizes in triclinic, space group P1 with a = 7.3668（12）, b = 10.1726（14）, c = 11.2264（15） A, a = 100.404（2）, b = 106.113（3）, g = 109.158（3）o, V = 728.48（19） A3, Mr = 966.26, Z = 1, F（000） = 470, Dc = 2.203 g/cm3, m（Mo Kα） = 3.585 mm-1, the final R = 0.0195 and w R = 0.0470（I 〉 2s（I））. Complex 1 is a 3D network with pcu topology with 1D porosity and rich hydrogen-bonding interactions. The proton conductivity of complex 1 was also studied under ~97% relative humidity and the different temperature conditions.

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.
