摘　　要：A new Na(I) coordination polymer,[Na2(Hpimdc)(H2 pimdc)(phen)2]n(1), has been synthesized by the reaction of NaOH with 2-propyl-4,5-imidazoledicarboxylic acid(H3 pimdc)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 H3 pimdc adopts two modes(singly deprotonated and doubly deprotonated) to coordinate with the Na(I) ion.The Na(1) ion is six-coordinated with three N atoms from a phen ligand and a H2 pimdc ligand,three O atoms from a Hpimdc ligand and two other different H2 pimdc 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 H2 pimdc ligand and other two different Hpimdc ligands. Complex 1 exhibits a 1 D chain structure built up by μ-H2 pimdc-and μ-Hpimdc2-ligands. The antitumor activities of complex 1 against human SGC7901, A549 and H08910 cells have been tested.
