A　coordination　polymer,　{[Cd2(H2Me4bpz)(ntcaa)2(H2O)]·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　π-π　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.　Graphical　Abstract:　[Figure　not　available:　see　fulltext.].　©　2012　Springer　Science+Business　Media　New　York.
