摘　　要：Two new 3D heterometallic (3d-4f) coordination polymers {[Ln2Cu(pydc)4(H2O)6]·2H2O}n [Ln = Eu (1) and Gd (2)] have been synthesized by hydrothermal reactions and characterized by elemental analysis, X-ray single-crystal analyses, and IR spectroscopy. X-ray crystal structure analyses show that 1 and 2 possess 3D networks and strong intramolecular hydrogen bonding interactions which was confirmed by thermogravimetric (TG) analysis.Two new 3D heterometallic （3d-4f） coordination polymers {[Ln2Cu（pydc）4（H2O）6]·2H2O}n [Ln = Eu （1） and Gd （2）] have been synthesized by hydrothermal reactions and characterized by elemental analysis, X-ray single-crystal analyses, and IR spectroscopy.
