Hydrothermal reaction of CuCN, K-3[Fe(CN)(6)] with 4-(6-amino-2-pyridyl)-1,2,4-triazole (apt) afforded a coordination polymer [Cu-7(CN)(7)(apt)(2)](n) (1), while solvothertlial reaction of CuSCN with apt in acetonitrile afforded a coordination polymer [Cu-2(SCN)(2)(apt)](n) (2). Complex 1 shows two-dimensional polymeric network with large hexagonal channels constructing by CuCN chains and tridentate apt ligands. Complex 2 shows two-dimensional polymeric framework assembled by ladder-like [Cu(SCN)](n) chains and bidentate apt ligands, in which thiocyanate acts as a tridentate bridging ligand. Both polymers are thermal stable and strong fluorescent in the solid state. (C) 2007 Elsevier B.V. All rights reserved.
