A novel U(Ⅵ)-K heteronuclear coordination polymer UO2K2(pdc)2· 3H2O (H2pdc=pyridine-2,6-dicarboxylic acid) has been synthesized hydrothermally and determined by means of IR, UV and X-ray single-crystal diffraction methods. The single-crystal X-ray analysis of the complex reveals that the crystal belongs monoclinic, space group C2/c with a=1.888 5(6) nm, b=1.490 0(5) nm, c=0.740 2(2) nm,β=111.104(10)°. The centered uranium atom and 3H2O] units are bridged by oxygen atoms to form three-dimensional chain coordination polymer. In addition, there
