摘要

Two new compounds, Ag(Hppdb)_n (1) and {Ag_2- (Hppdb)2(bpe) 5.5H2O}_n(2)H2ppdb = 2,3-fpyrazino1,10 phenan- throline-2,3-dicarboxylic acid, bpe = trans-1,2-bis(4-pyridyl)ethylene, were synthesized and characterized. In 1, Hppdb-ions link Ag ~Ications to form an infinite 1D -Ag-(Hppdb)-Ag-_n chain, furthermore, the dimensionality is extended to 2D layers through synergistic π-π stacking, hydrogen-bonding and weak Ag O interactions. Correspondingly, the dimeric (Ag)(Hppdb)_2 subunits in 2 are connected by bpe ligands to generate a loop-link-shaped 1D chain motif, which is further joined through a R_22(18)C-H O hydrogen-bonding ring to afford interesting diagonal/diagonal inclined catenation 2D + 2D → 3D supramolecular architectures. In addition, solid-state properties such as photolumines cence and thermal stability of the two compounds were studied.
