A new metal-organic complex Pb(cbba)2(phen)2 (1, H2cbba=2-(4′-chlorine-benzoyl)benzoic acid, phen= 1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The compound crystallizes in orthorhombic, space group Pbcn with a=1.474 49(7) nm, b=0.953 90(4) nm, c=3.031 65(14) nm, V=4.264 1(3) nm3, C52H32Cl2N4O6Pb, Mr=1 086.91, Dc=1.693 g·cm-3, μ(Mo Kα)=4.141 mm-1, F(000)=2 144, Z=4, the final R=0.018 3 and wR=0.045 7 for 3 582 observed reflections (I>2σ(I)). In the crystal structure, the lead atom is six-coordinated with two carboxylate oxygen atoms from different cbba ligands and four nitrogen atoms from different phen ligands, showing a distorted octahedral geometry. Furthermore, 1 shows yellow photoluminescent property at room temperature.
