An　isomorphous　series　of　three　novel　lanthanide　coordination　polymers　[Ln(PCPA)(3)(glycol)](n),　[where,　Ln　=　La(1);　Nd(2);　Gd(3);　PCPA　=　p-chlorophenoxyacetate]　have　been　synthesized　under　hydrothermal　conditions　and　characterized　by　elemental　analyses,　IR　spectra,　TG　analysis,　fluorescence　spectra　and　single　crystal　X-ray　diffraction　analysis.　The　results　reveal　that　all　of　them　form　a　chain-like　one-dimensional　structure.　Photoluminescent　properties　for　the　complexes　are　also　reported.
