AbstractA new coordination polymer {[Eu2(Cl2C6H3OCH2COO)6(H2O)4]·(DMF)4·(H2O)2}nwith 2,4‐dichlorophenoxy acetic acid as the ligand has been synthesized. The crystal data for this complex are as follows: monoclinic, space groupP2(1)/n,a=0.86474(17) nm,b=3.2475(7) nm,c=1.3843(3) nm,β=92.81(3) °,V=3.8827(13) nm3,Dc=1.718 g/cm3,Z=2,µ(Mo Kα)=2.093 mm−1,F(000) =2008, final discrepancy factorsR1=0.0454,wR2=0.1165. The crystal structure shows that the title complex forms one‐dimensional chain structure by bridging 2,4‐dichlorophenoxy acetic a...
