The title compound [NdK(btec)(H2O)2]n 1 was synthesized via the hydrothermal reaction of Zn(OAc)2·H2O, Nd(NO3)3 and KOH with 1,2,4,5-benzenetetra-carboxylic acid (H4btec), and characterized by elemental analysis and infrared spectra.The crystal of 1 crystallizes in monoclinic, space group P21/c with a = 8.9023(3), b = 7.8954(1), c = 17.6249(5)A, β = 91.857(1)o, V = 1238.16(6) -3, Z = 4, C10H6KNdO10, Mr = 469.49, Dc = 2.519 g/cm3, F(000) = 900 and μ(MoKα) = 4.585 mm-1.The final R = 0.0404 and wR = 0.0832 for 2197 observed reflections with I > 2σ(I) and R = 0.0431 and wR = 0.0854 for all data.X-ray diffraction reveals that the btec ligand serves as a (16-bridging ligand to link the Nd(III) and K(I) atoms into a three-dimensional coordination polymer.Photoluminescent investigation shows that the title compound displays strong emission in the blue region, which may be attributed to an intraligand emission state.
