The reaction of CdCl3.2.5H2O with 3,5-pyrazoledicaiboxylic acid under hydrother-mal conditions produce a novel three-dimensional(3-D) coordination polymer [Cd2(C5H2O4N2)2.2H2O]n.The title compound crystallizes in the monoclinic system,space group P21/c with a = 6.422(4),b = 12.334(7),c = 8.936(6) ,β = 104.793(7)°,V = 684.4(7) 3,Z = 4,Dc = 2.761 g/cm3,μ = 3.181 mm-1,F(000) = 544,R = 0.0248 and wR = 0.0624.In the crystal structure of the title compround,molecules are linked through N-H...O hydrogen bonds,forming chains running along the a axis.Every Cd(Ш) coordinates with four molecules of ligand and one water molecule,forming a pentagomal-bipyramidal geometry.
