A coordination polymer of [Cd{5-(NO2) sal}2(2,2'-bipy)]n(5-(NO2) sal=5-nitrosalicylate,2,2'-bipy=2,2'-bipyridine) was synthesized by hydrothermal reaction and characterized by elemental analysis,IR and X-ray diffraction single crystal structure analysis.The title complex crystallizes in monoclinic with space group C2/c,a=2.730 8(16) nm,b=1.272 3(5) nm,c=0.674 5(3) nm,β=96.73(2) °,V=2.327(2) nm3,Z=4,R=0.022 2,wR=0.057.The 5-nitrosalicylate anions doubly bridge the Cd(Ⅱ) atoms to form one-dimensional polymeric chain with the repeated eight-membered ring units(Cd-O-C-O) 2.The crystal structure is stabilized by intra-and interchain hydrogen bonds interactions.CCDC:694568.
