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.展开更多

The Crystal crystallizes in monoclinic system, the space group is C2/c, with the crystal cell parameters a=1.175 1(1) nm, b=0.551 0(1) nm, c=1.827 7(2) nm, β=96.14(2)°, and V=1.176 6(3) nm3,, Mr=372.60, R=0.045 9, wR=0.127 9. The Cd( ion has a trigonal prism coordination configuration that defined by four carboxyl O atoms from two different p-BDOA2- ligands and two water molecules. Adjacent Cd( ions are linked by carboxylate groups with the bidentate coordination mode, giving rise to a chain structure with the adjacent Cd...Cd distance of 1.526 3(5) nm. Furthermore, such chains are linked by hydrogen bonds to form supramolecular network. The results of PL and TG show that the complex exhibits intense fluorescent emissions and its chain skeleton is thermally stable up to 419 K. CCDC: 220443.展开更多
