| Abstract: A novel 1-D coordination polymer of {[Cd(C14H9O3)2]·2H2O}n was synthesized and characterized by elemental analysis, IR, TG and X-ray single crystal diffraction. The title complex crystallizes in orthorhombic system with space group Pbcn, a=2.618 8(5) nm, b=1.326 4(3) nm, c=0.716 52(14) nm. V=2.488 9(9) nm3. The final indices are R=0.043 1 and wR=0.172 1. The cadmium atom is six-coordinate involving six oxygen atoms from different 9-hydroxy-fluorene-9-carboxylate ligands, forming a distorted octahedral geometry. The cadmium atoms are bridged by 9-hydroxy-fluorene-9-carboxylate ligand, forming a one-dimensional chain along c axis. The distance of adjacent Cd…Cd atoms is 0.377 1 nm. The results of TG analysis show that the title complex was stable under 249.7 ℃. CCDC: 235967. |
