Two new compounds, [Ag(Hppdb)] n ( 1 ) and {[Ag 2 (Hppdb) 2 (bpe)] · 5.5H 2 O} n ( 2 ) [H 2 ppdb = [2,3‐f]pyrazino[1,10]phenanthroline‐2,3‐dicarboxylic acid, bpe = trans ‐1,2‐bis(4‐pyridyl)ethylene], were synthesized and characterized. In 1 , Hppdb – ions link Ag I cations 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 2 2 (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 photoluminescence and thermal stability of the two compounds were studied.
