Abstract :The new coordination polymers arranged from flexible pamoic acid, namely {[Niinsert ignore into journalissuearticles values(µ-pam);insert ignore into journalissuearticles values(en); 2 ]·H 2 O} n insert ignore into journalissuearticles values( 1 );, insert ignore into journalissuearticles values(H2pam= pamoic acid, en= ethylenediamine );, have been synthesized under hydro/ solvothermal conditions and characterized by elemental analysis, simultaneous TG, DTA techniques, IR spectroscopy , and X-ray crystallography.  X-ray single crystal structure analysis of 1 shows that t he Niinsert ignore into journalissuearticles values(II); ions are bridged by pamoic acid ligands to generate 1dimensional insert ignore into journalissuearticles values(1D); coordination polymer running parallel to the direction, with the Ni∙∙∙Ni separation is 14.057 Å. Adjacent 1D chains are connected by N-H···O and O-H···O hydrogen bonds to establishing 3 dimensional insert ignore into journalissuearticles values(3D); supramolecular network. An infinite 3D supramolecular network in 1
