Weifang University, Weifang 261061, China)ABSTRACT A new Na(I) coordination polymer, [Na2(Hpimdc)(H2pimdc)(phen)2]? (1), has

been synthesized by the reaction of NaOH with 2?propyl-4,5-imidazoledicarboxylic acid (H3pimdc)

and 1,10?phenanthroline (phen). The Na(I) coordination polymer 1 was characterized by

single-crystal X-ray diffraction analysis and elemental analysis. In 1, the bridged ligand Hspimdc

adopts two modes (singly deprotonated and doubly deprotonated) to coordinate with the Na(I) ion. The Na(l) ion is six-coordinated with three N atoms from a phen ligand and a H2pimdc ligand,

three O atoms from a Hpimdc ligand and two other different H2pimdc ligands. The Na(2) ion is

also six-coordinated with three N atoms from a phen ligand and a Hpimdc ligand, three O atoms

from a H2pimdc ligand and other two different Hpimdc ligands. Complex 1 exhibits a ID chain

structure built up by 2pimdc_ and //-Hpimdc2- ligands. The antitumor activities of complex 1

against human SGC7901, A549 and H08910 cells have been tested.Keywords: 2?propyl-4,5-imidazoledicarboxylic acid, Na(I) coordination polymer, synthesis,

structure and property of coordination polymers with 2-propyl-4,5-imidazoledicarboxylic acid. Our

ligands exhibited intriguing structures and distinc-
