A　Ce-III　linear　complex　of　N-hydroxy-1,8-naphthalenedicarboximide　(HL)　has　been　synthesized　with　acenaphthoquinone　dioxime　(acndH2)　under　solvothermal　conditions,　in　which　L　is　generated　by　a　series　of　in-situ　reactions　starting　from　acndH(2).　X-ray　crystallography　reveals　the　coordination　chains　of　Ce-III　ions　are　assembled　into　a　3D　supramolecular　framework　via　pi　middotmiddotmiddot　pi　interactions.　The　title　complex　has　been　characterized　by　IR　and　UV-Vis　spectra　and　thermogravimetric　analysis　(TGA).　Furthermore,　the　fluorescent　properties　study　demonstrated　a　ligand-based　emission　of　the　Ce-III　complex　with　similar　to　6　nm　blue-shift　compared　with　the　emisision　of　the　HL　ligand.
