A　novel　two　dimensional　coordination　polymer　[Eu(PCPOA)(3)　(H2O)](n)　was　synthesized　under　hydrothermal　condition.　Based　on　the　determination　of　the　structure,　the　2D　correlation　FTIR　spectra　with　the　perturbation　of　magnetism　and　the　2D　correlation　fluorescence　spectra　with　the　perturbation　of　temperature　were　investigated.　The　energy　bonds　were　calculated　using　CASTEP　Program　of　Material　studio.　The　Europium　ions　are　nine-coordinated　and　the　ligands　adopted　two　different　modes　to　connect　the　Eu3+　ions　to　2D　layer　structure.　The　study　of　the　2D-FTIR　reveals　that　the　carboxylates　coordinate　with　the　center　ions　not　only　as　monodentate,　but　also　as　bidentate　chelate.　The　2D　fluorescence　spectra　indicates　that　the　transition　of　D-5(0)　-＞　F-7(2)　is　influenced　intensively　by　the　perturbation　of　temperature.
