A　new　coordination　polymer,　[Cd-4(atz)(6)(PTA)](n)　has　been　firstly　synthesized　by　employing　mixed-ligand　of　terephthalic　acid　(PTA)　with　the　in-situ　generated　ligand　of　5-amino-tetrazolate　(atz(-)).　Compound　1　represents　a　3D　microporous　framework　constructed　from　Cd-tetrazolate　subunits　and　the　subunits　are　bridged　by　PTA　and　atz　ligands.　When　the　subunit　was　collided　into　node,　compound　1　possesses　an　unprecedented　3,　9-connected　topological　network.　Furthermore,　the　investigations　of　thermal　stability　and　luminescent　property　of　complex　1　indicate　that　compound　1　may　be　an　excellent　candidate　for　potential　blue-light　emitting　material.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
