Abstract: A new 3D rare-earth coordination polymer[Ce2(H2btc)(btc)(H2O)2]n (1) was hydrothermally synthesized and its structure was characterized by the single crystal X-ray diffraction. Compound 1 crystallizes in a triclinic crystal system,space group P 1 with a=0.641 17(13) nm, b= 0.939 41(19) nm, c=0.957 97(19) nm, α =103.888(17)°, β =74.57(3)°, γ =76.71(3)°, V= 0.540 98(19) nm3, Z=1, R= 0.026 4,wR2=0.077 9. The three-dimensional compound 1 is built by linking one crystallographically independent nine-coordination Ce(Ⅲ) subunit through the btc and the H2btc ligands. Each nine-coordinate Ce(Ⅲ) unit is a distorted tricapped trigonal prism,of which eight oxygen atoms belong to six different carboxylate groups of btc or H2btc and a water molecule,with the Ce(Ⅲ)—O bond lengths ranging from 0.240 3(3) nm to 0.263 6(3) nm.
