Abstract：

Two　3D　coordination　polymers　with　different　structure　motifs,　[Zn2(PCPA)2(IN)2]n　(1)　and　[Co(PCPA)(IN)]n　(2)　(PCPA=p-chlorophenoxyacetate,　IN=isonicotinate),　first　constructed　from　mixed　rigid　and　flexible　carboxylate　ligands,　have　been　obtained　under　hydrothermal　condition　and　characterized　by　elemental　analyses,　IR　spectra,　thermogravimetric　analysis,　fluorescent　spectra　and　single　crystal　X-ray　diffraction　analysis.　The　most　intriguing　structural　feature　is　that　each　complex　exhibits　both　infinite　helical　Zn(μ2-carboxylate)　or　Co(μ3-carboxylates)　chain　units　with　21　helices　and　zigzag　M2(IN)2　(M=zinc　and　cobalt)　chain　units　by　reason　of　two　different　carboxylate　ligands　coordinating　to　metal　centers.　Additionally,　compounds　1　and　2　show　similar　blue　fluorescence　in　the　solid　state　at　room　temperature.　©　2006　Elsevier　Inc.　All　rights　reserved.
