| Abstract: A new two dimensional samarium coordination polymer [Sm(1,4-bda)1.5(phen)(H2O)]n (1) (1,4-H2bda=terephthalic acid; phen=1,10-phenanthroline) was synthesized by hydrothermal method. X-ray single crystal diffraction revealed that the Sm(Ⅲ) ions coordinate with six oxygen atoms and two nitrogen atoms. Five coordinated oxygen atoms on each Sm(Ⅲ) ion are from five 1,4-bda anions and the other one from water molecule. The two nitrogen atoms are from phen. Each Sm(Ⅲ) ion is chelated by one phen ligand. The 1,4-bda anions show two different coordination ways. Complex 1 crystallizes in triclinic system, P1 space group with a=1.030 72(6) nm, b=1.086 75(7) nm, c=1.139 83(8) nm, α=107.759(6)°, β=91.886(5)°, γ=112.878(6)°. The compound exhibits strong fluorescence under excitation of ultraviolet light. CCDC: 869856. |
