Phenanthroline (HL) and Pb (NO3) were synthesized under hydrothermal conditions using 2,10-phenanthroline derivative 2- (2-carboxyphenyl) ) 2, a complex [PbL2] n (1) was synthesized and its structure was characterized by IR, elemental analysis and single crystal X-ray diffraction. The complex 1 belongs to the monoclinic system with a space group of P21 / c and the unit cell parameters a = 1.345 9 (9) nm, b = 0.709 4 (5) nm, c = 3.265 5 (K = 10) °, V = 3.074 0 (4) nm3, Z = 4, C40H22N8O4Pb, Mr = 885.85, Dc = 1.914 g · cm-3, μ (MoKα) = 5.551 mm-1, = 1.038, R = 0.027 0, wR = 0.058 1 with 5 067 observable points (I> 2σ (I)). Structural analysis shows that complex 1 is a two-dimensional layered structure. In addition, the thermal stability and luminescent properties of the complexes were also studied.
