The hydrothermal reaction of pyridine-3,4-diearboxylic acid (pydcH2),4,4'-bipyridine and GdCl3·6H2O yield a novel gadolinium coordination polymer{[Gd2(pydc)2(μ3-OH)2(H2O)2]·H2O}n(1).The compound was charactefized by elemental analysis,thermal analysis,IR spectra and single-crystal X-ray structure analysis.The crystal of the Gd(Ⅲ)complex belongs to triclinie system,space group P1 with:a=0.796 25(16)nm,b=0.944 46(19)nm,c=1.2621(3)nm,α=76.50(3)°,β=84.95(3)°,γ=83.04(3)°,Z=2,V=0.9144(3)nm3,Dc=2.669g·cm-1,μ=7.269mm-1,F(000)=692,and R1=0.0333,wR2=0.062 3.The crystal structure revealed that compound 1 has a 2D layer structure incorporating 1D Gd-O-Gd double chain,and hydrogen bonding interactions result in the former of 3D supramolecular network structure.CCDC:669079.
