A　coordination　polymer,　{[Cd-2(H(2)Me(4)bpz)(ntcaa)(2)(H2O)]center　dot　H2O}(n)　(1),　has　been　synthesized　by　hydrothermal　reaction　of　cadmium　sulfate　octahydrate　with　a　flexible　ligand,　3,　3＇,　5,　5＇-tetramethyl-4,　4＇-bipyrazole　and　an　auxiliary　O-donor　ligands,　naphthalene-4,5-dicarboxylic　acid-1,8-anhydride.　Naphthalene-4,5-dicarboxylic　acid-1,8-anhydride　comes　from　the　in　situ　dehydration　of　the　naphthalene-1,4,5,8-tetracarboxylic　acid　in　the　hydrothermal　reaction.　Complex　1　exhibits　a　2D　wave-like　layer　structure　based　on　tetranuclear　Cd4O4　cluster　units.　The　2D　wave-like　layers　are　further　held　together　by　face-to-face　pi-pi　interactions　between　the　naphthalene　rings　and　intermolecular　hydrogen　bonds　to　generate　a　3D　supra-molecular　network.　The　luminescent　property　of　complex　1　was　investigated　in　the　solid-state　at　room　temperature.　.
