It crystallizes in monoclinic, space group P21/c with a = 10.1043（11）, b = 14.3162（15）, c = 17.6061（18）, β = 95.3990（10）°, V = 2535.5（5）3, Z = 4, C31H17FN4O4Pb, Mr = 735.68, Dc = 1.927 g/cm3, F（000） = 1416, μ（MoKa） = 6.709 mm-1, R = 0.0201 and wR = 0.0489. The 1,4-ndc dianions link neighboring Pb（II） atoms in a bis-chelating mode, yielding a one-dimensional chain structure along the c axis. The C-H···π interactions between the carbon atom of L ligand and the benzene ring of 1,4-ndc lead the one-dimensional chains to form a two-dimensional supramolecular layer. The π-π interactions between L ligand and 1,4-ndc ligand make the two-dimensional layers generate a three-dimensional supramolecular architecture. Additionally, the N-H···O hydrogen bonds further stabilize the structure of 1.展开更多

The L2 dianions bridge neighboring Pb（Ⅱ） atoms to form a two-dimensional layer structure. The π-π interactions between the L1 ligands of neighboring layers led to a three-dimensional supramolecular architecture. The IR and TGA of the complex have been studied in detail.展开更多
