Two　Zn(II)　and　Cd(II)　compounds　with　the　in-situ　generated　ligand　of　5-amino-tetrazolate　(atz　-)　were　prepared　from　the　hydrothermal　reactions　of　the　corresponding　Cd　or　Zn(II)　salts　with　phenylcarboxylate,　and　characterized　by　elemental　analysis,　IR　spectroscopy,　and　TGA.　The　results　of　X-ray　crystallographic　analysis　reveal　that　compound　[Zn　2(BZA)(atz)　2(OH)]　n　(1)　(BZA=benzoic　acid)　presents　a　two-dimensional　(2D)　hcb　topological　network　constructed　from　the　ZnN　2O　2　tetrahedra.　In　compound　[Cd　6(atz)　6(PTA)　3]　n　(2)　(PTA=terephthalic　acid),　the　identical　[Cd　3(atz)　3)]　3　n　clusters　are　connected　by　atz　ligands　to　generate　a　2D　cationic　layer,　and　the　neighboring　cationic　layers　are　pillared　by　PTA　giving　birth　to　3D　network.　After　simplifying,　the　complicated　3D　network　of　2　can　be　presented　as　an　unprecedented　(4,　4,　10)-connected　trinodal　topology.　The　formations　of　the　structures　show　a　good　example　that　using　the　combination　of　the　in-situ　generated　ligand　and　other　coligand　synthetic　strategy　can　construct　interesting　topological　structures.　The　thermal　stabilities　and　fluorescent　properties　of　the　complexes　have　also　been　studied.　©　2012　Elsevier　Inc.　All　rights　reserved.
