英文摘要	National Natural Science Foundation of China [20721001]; MSTC [2007CB815301]; Two novel coordination polymers (CPs) {[Ag(bga)(pzc)]center dot 0.5H(2)O}(n) (1) and [Ag-2(bga)(2)(pzdc)(H2O)](n) (2) (bga = benzoguanamine, Hpzc = pyrazine-2-carboxylic acid, H(2)pzdc pyrazine-2,3-dicarboxylic acid), have been prepared and characterized. Single-crystal X-ray structural analysis reveals that complex 1 is a novel 1D single-strand helical chain constructed from mu(2)-N,N'-bga and mu(1)-(eta(2)-N,O)-pzc ligands. Complementary N-H center dot center dot center dot N hydrogen bonds link the alternate left-and right-handed helical chains to form the final racemic 2D supramolecular sheet. Complex 2 is a 1D U-shaped chain with mu(1)-N-bga and mu(3)-(eta(2)-N,O), N', (eta(2)-O',O '')-pzdc ligands. Each U-shaped single chain containing [Ag-2(bga)(2)(pzdc)(H2O)] subunits is staggered along the c axis producing large interstices between adjacent bga ligands which accommodates two identical chains from both sides by interdigitation of the dangling bga ligands, producing a 1D -> 2D interdigitated supramolecular sheet through complementary N-H center dot center dot center dot N hydrogen bonds. The structural dissimilarity between 1 and 2 is caused by the different auxiliary pyrazine-carboxylate ligands and different coordination modes of bga ligand. The complementary N-H center dot center dot center dot N hydrogen bonds play prominent roles in the formation of the final racemic 2D supramolecular sheet of 1 and 1D -> 2D interdigitated sheet of 2. In addition, the thermal stabilities and emissive behaviors of them were also investigated.
