Abstract

The new coordination polymers arranged from
flexible pamoic acid, namely {[Ni(µ-pam)(en)₂]·H₂O}_n
(1), (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 the Ni(II) ions
are bridged by pamoic acid ligands to generate 1dimensional (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 (3D) supramolecular network.
