The　title　complex,　[Zn(C18H12N2)(C8H4O4)](n),　consists　of　a　one-dimensional　zigzag　[Zn(tpa)(quin)](n)　chain　(tpa　=　terephthalate　and　quin　=　2,2＇-diquinolyl)　with　a　pitch　of　17.907　(2)　angstrom.　The　tpa　ligands　bridge　two　Zn　atoms　in　alternately　bis(bidentate)　and　bis(monodentate)　coordination　modes.　Each　Zn　atom　is　coordinated　by　two　N　atoms　from　a　chelating　quin,　two　O　atoms　from　one　bis(bidentate)　tpa　and　one　O　atom　from　one　bis(monodentate)　tpa.　The　five-coordinate　Zn　geometry　can　be　best　described　as　distorted　trigonal-bipyramidal.
