A series of silver(I) coordination polymers have been synthesized by the combination of an extended 2,4'-bipyridyl linker trans-1-(2-pyridyl)-2-(4-pyridyl)ethylene (bpe) and different benzenedicarboxyl tectons, including isophthalic acid (H(2)ip), 5-sulfoisophthalic acid (H(3)sip), terephthalic acid (H(2)tp), 2-aminoterephthalic acid (H(2)ata), and 2-bromoterephthalic acid (H(2)bta). Single-crystal X-ray diffraction indicates that the structural patterns of these polymeric complexes diversify from two-dimensional (2-D) (3,4,5)-connected (for 2) or 6(3) (for 3 and 4) layers to three-dimensional (3-D) (10,3)-b (for 1) or 8-nodal self-penetrating (for 5) networks. Interestingly, the Ag-1 centers can show various coordination spheres such as linear, trigonal, tetrahedral, and square-pyramidal geometries. The results clearly reveal that the dicarboxyl building blocks with different dispositions or the carboxyl sites and uncoordinated substituent groups, are the crucial factors for structural assemblies of such extended frameworks. Solid-state properties for these crystalline materials have also been investigated, which display modest thermal stability and strong fluorescent emission at room temperature.
