Abstract：A novel porous coordination polymer [Nd2(C6H8O4)3(H2O)2]n·n(4,4’-bpy) was synthesized by hydrothermal synthesis reaction of hexyl acid, 4,4’-bpy with NdCl3·XH2O. The structure was characterized by elemental analysis, thermal gravimetric analysis, IR spectroscopy, and X-ray single crystal analysis. The crystal data are of an orthorhombic crystal system, Pbcn space group. Crystallographic data are: a =2.201 2 nm(6), b=0.777 8 nm(2)，c=1.972 4 nm(5), α=β=γ = 90°, V=337.70 nm(15)3, Z=4, Dc=1.796 g·cm-3, μ= 3.108 mm-1, F(000)=1 800, R1=0.043 0 and wR2=0.056 0. X-ray analysis reveals that three-dimensional porous nets were formed between Nd3+ and Nd3+ by carboxyl of hexyl acid.
