A unique metal-organic framework(MOF) [Eu_2(L)_3(phen)_2]_n(1, H_2L = 4,6-dibenzoylisophthalic acid, phen = 1,10-phenanthroline) has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray analysis, elemental analyses, powder X-ray diffraction, TGA measurement as well as IR spectra. The crystal is of triclinic system, space group P1, C_(90)H_(52)Eu_2N_4O_(18), M_r = 1781.32, a = 9.8697(4), b = 16.7466(6), c = 22.2556(10) ?, α = 87.113(3), β = 77.575(5), γ = 89.458(3)°, V = 3587.8(3) ?~3, Z = 2, D_c = 1.649 g/cm~3, F(000) = 1780, μ(MoKα) = 1.813 mm~(-1), Rint = 0.0181, R = 0.0260 and wR = 0.0592 for 14000 observed reflections with I > 2σ(I). X-ray analysis shows that the title compound exhibits a 2D layer structure linked by L ligands with two coordination modes and two distinguished conformations, and further linked into a 3D supramolecular architecture through C–H···O weak interactions between hydrogen of phen phenyl ring and the carboxylate oxygen atom of adjacent sheets. In addition, the luminescence property of 1 was investigated.
