摘要
The cerium based metal-organic framework, Ce(phen)(DA)(OX)(0.5)(H2O)center dot 2H(2)O (1) (DA = diphenic acid, OX = oxalic acid), was obtained by hydrothermal reaction of the mixture of CeCl3 center dot 7H(2)O, diphenic acid (DA) and oxalic acid (OX) and 1,10-phenanthroline (phen) in 1:1:1: molar ratio at 140 degrees C for 96 h. The crystal of Ce(phen)(DA)(OX)(0.5)(H2O)center dot 2H(2)O crystallizes in triclinic, space group pi with with cell parameters a = 8.602(14) angstrom, b = 12.62(2) angstrom, c = 13.54(2) angstrom, V = 1282(3) angstrom(3) and Z = 1. X-ray diffraction reveals that in complex 1, Ce1 is a nine-coordinated tricapped trigonal prism made up of two nitrogen from phen ligand, two oxygen atoms from the same carboxylate group attached on a diphenic acid ligand, two oxygen atoms from two carboxylate groups attached on another ligand, two oxygen atoms from an oxalic acid ligand and one oxygen atoms from a water molecule. The centers Ce3+ ions are linked by diphenic acid and oxalic acid ligands into one-dimensional infinite and neutral chains.
