摘要

Five novel SrII-LnIIIheterometallic coordination polymers based on pyridine-2,6-dicarboxylic acid(H2pda)and imidazole(im),namely,[LnSr(pda)3(H2O)5]·Him·C2H5OH·3H2O(Ln=Nd(1);Pr(2)),[Ln2Sr(pda)6(H2O)5]·4Him·C2H5OH·5H2O(Ln=Nd(3);Pr(4)),and[ErSr(pda)3(H2O)4]·Him·3.5H2O(5),have been prepared and structurally characterized.X-ray crystallographic analyses revealed that these complexes display three varieties of 1-D chain structures.Several types of hydrogen bonding interactions are found for 1~5,which connect the1-D chain structures to form 2-D supramolecular networks.
